Mini Tool Reviews: #2 Central Pneumatic 92924 Vacuum Brake Bleeder.

[@routedworld]

Have one of these from HF and love it. Mine comes with a feeding system for the Master Cylinder. I clean and wipe it down every time I use it. The only problem I've had is with the black rubber head. It either doesn't fit right or blocks my wrench so I never use it and just put the hose directly over the fitting. Works fine that way.

[@gwdeals]

I have one of these and it works great. I have used it on at least 20 brake jobs. It does use a lot of air so you need a decent compressor. Mine has a 30 gallon tank. You need to run this bleeder at a constant 90 psi. Sometimes you will see air bubbles coming through the line because it is not sealing 100% around the bleeder screw. But if you pull enough fluid through you will be fine. Great tool.

[@jsjizza1540]

Love this tool!!!! Its the EASIEST way to bleed brakes when you are by yourself!!! Ive had this since last spring. Thank you tech

[@Fireship1]

Bought this to bleed hydraulic clutches. This is where this tool really shines. Anyone who has ever tried to bleed a ford ranger or Mazda B series truck clutch will LOVE this tool. Those models must be one of the most challenging clutch bleeds of all time. Ford techs know what I'm talking about!

[@JeffGoldSr]

I have 2 of these at my shop. They work well. The only problem that I've experienced is a blockage in the metal connector on the cap. just use a small pick to clear it. It does come with a refill container and some attachments to fit different master cylinders and works pretty well. Good video, thank you.

[@kody530]

I bought one a couple of weeks ago. I just used it today to get the fluid out of the master cylinder, it worked great.

[@Organplayer1947]

Yours is the first application video that shared a lot of experience using this tool. You were clear regarding leaks and the importance of maintaining positive vacuum. I even saw a decent fluid flow immediately. My problem with many of these devices has been leaks at hoses and the bleeder. So..I am going to try this unit. I hope to get my brakes working well enough to bring my '63 Imperial le Baron (restored) to my mechanic who builds hotrods and does custom work. He is one of the very very few in town!!! He can pro bleed and adjust my brakes!! PTL!!! Thank you for this VERY informative honest forthright video sir!!

[@ronhart4166]

Great advice. I have the "vacula " bleeder. It is a little larger and it also came with a resivior bottle for master cylinders that gravity bleeds into the master cylinder while you flush system. Works great.

[@george420]

Best video I've seen yet on using this particular tool.

[@jacobbrown3861]

Literally just bought this from my local harbor freight. 35 bucks. Replaced an abs pump and rear brake line to the axle on a 2004 gmc sierra. Entire system was bled within 15min. Performed automated bleed on the abs module afterwards. Brakes worked great!!! Very good tool.

[@jinto_reedwine]

I've been using the two person method and always wanted an affordable alternative. This looks awesome! I just repair my own cars and occasionally help a friend so it never seemed worth it to spend $100+ for a tool that would only bleed brakes. Can't wait to pick one of these up the next time I bleed brakes :-).

[@2011spaceage]

It sounds like a must have tool for people like me who feels better doing this myself, because I know the job was done correct and no corners-cut. I've known a few mechanics and none had the professionalism toward their job like you.

[@ragtie6177]

Excellent video. Installing new calipers and lines & pads on my 2010 Escape tomorrow. And just bought the exact unit from Harbor Freight.

[@mikeramsey9747]

Based on your recommendation I have purchased this brake bleeder kit and I'm glad that I will be able to bleed the brakes by myself.

[@gatorgotme]

Brian, I really REALLY like your channel! Thank you for taking the time to help the rest of us like this. Very good instruction! Oh, and Merry Christmas!

[@kylelentine]

thank you for taking the time to make a nice instructional and tool review video

[@ratbert86]

Bought one of these this weekend to purge contaminated brake fluid from a Toyota Sequoia and it worked flawlessly. Should have bought one of these years ago. This thing uses a LOT of air (it kept my 30 gallon comp busy) so if you have a small compressor, you'll be disappointed. I also have the HF A/C vacuum pump - I wonder if I could somehow connect it to the reservoir so I don't have to run the compressor. Hmmmm

[@moedogg27]

Thanks for showing me that I had just bought one a couple days ago and watch this on KZbin great information I will never have to step on a f****** brake pedal again I've had air in the system before and had to ask my dad to pump the brake pedal and it took hours sometimes and certain models of vehicles to get the air out can't wait to try this I can't get the air out of my Sandrail in the brake system due to master cylinder being lower than the rest of the system so I'm excited to try this

[@rrbrian222]

Thanks, I just purchased one of these for two upcoming brake services. Great video as always, Brian.

[@purpleguy2159]

Great demo, out to the garage I go! Thanks for taking the time to put this video together!

[@Wyatt_K]

works well on differentials especially on a front differential with no drain.

[@petemoss9693]

Hello Brian, Watching this video I am sold on buying this pressure bleeding tool, just as you mentioned in this video of having to call a friend to help push down on the peddle then buying a hand held tool to bleed the system to do it my self so now I am going to Harbor Freight - sure glad I happen to see this video of yours .

[@gbush1620]

Here's an issue. For Home DIY, I don't have air power source connecting to the pump. I prefer manual pump for bleeding.

[@apocalysp]

best video on the subject of brake bleeding

[@Guillotines_For_Globalists]

I recently did four complete brake system flushes using the Mityvac from Harbor Freight. At the end of it, my hands definitely got a workout, and I wished that I had bought this instead, since it uses compressed air to do all of the pumping for you. The next time that I get that 25% off coupon, this will be in my basket!

[@stoggy4839]

You should be careful with the exhaust from the bleeder. A carburator works by spraying small areated gas into the cylindar. So More then likely you are spraying small bubbles of break fluid everywhere, which is acidic. I would but something over the exhuast to at least slow it down. Maybe a rag or even a hose.

[@scorps9398]

You sold me to go buy one, right now! Good video thank you!

[@jonathancleaves5714]

Great video well explained. Used the same system on my caddy slave cylinder 😉👍

[@BobbyCulpepper.srv3fender]

im a pressure bleeder guy, i never liked vacuum bleeders for bleeding brakes, half the time it just sucks air around the threads of the bleeder screw, the other half the time it will create a vacuum in the line so if the hose comes off then air gets pulled in the line. Plus you have to go up and down keeping the master full, and the refillers they make never work right. With a pressure bleeder i can attach it to the master , open all 4 bleeders if i want and walk away for 5 mins and come back when the fluid is clear, and 99% of the time theres no air in the system left. its also great for bleeding new master cylinders and hydraulic control units. The worst thing in the world is getting all done with a brake job and then having to pull it back in to your bay and bleed it all over again because the pedal is squishy.

[@FordTechMakuloco]

srv3fender This one sucks slow enough you can just add brake fluid when needed you don't have to keep running up there to check it.

[@Logjam5]

Nice demo, good suggestions for alternate uses.

[@Santos-ek8md]

Great vid Brian. In the beginning I thought you wanted to be anonymous lol. This is a great tool. I’ve been researching vids online about it to make the better purchase. Most ppl agree to this device almost always. Thanks again,

[@Texasknowhow]

Just found your channel, awesome instructional video here on using a vacuum bleeder. Good pace, post editing, easy to listen to (some folks drone on forever) - overall very nice video. I've done my last manual or hand pump brake bleed! Heading to get one at Harbor Freight as I need it today (otherwise everyone click on his link above). I'll mention you in my next video where I use mine. Thanks man, Clay

[@petrocksgarage]

Cool tool. I'd be worried about running the master cylinder dry too easily with the power bleeder. I like hand vacuum pumps for brake bleeding for better flow and vacuum pressure control, although the reservoirs do tend to be a little small, IMO. The power bleeder, with its huge reservoir, would be awesome at sucking tranny fluid out of the transmission through the filler neck before dropping the pan to reduce the chance of spilling fluid everywhere. Or to remove excess engine or tranny fluid if you mistakenly add too much.

[@FordTechMakuloco]

Pet Rock's Garage Nope not on this one it doesn't suck it down that fast.

[@sigor2011]

FordTechMakuloco I don't know if you did not get a complete kit but mine came with a bottle that is about 500 cc where you put brake fluid, you stick that bottle upside-down into the brake reservoir and open a valve and it gives you plenty of extra brake fluid to bleed with out running back and forward, also because it is high up, you can see if from further away for level. This only works if you have a vertical access to the brake fluid reservoir of course.

[@ronchadwick8552]

On my way to HF. 👍 great video sir

[@8power0]

CAN YOU TELL ME ,,, CAN I USE THIS TOOL ON A 1994 2.3 LITER 4 CYLINDER FORD RANGER MASTER CLUTCH CYLINDER FOR BLEEDING THE CLUTCH SYSTEM, THANK YOU FOR ANY HELP ??????????

[@cobraninetysix3883]

Great video. I have this tool and the one question I have is how do you know when the air is outta of the line. The hose never really shows a solid stream of fluid while operating the unit. Old school method of pumping the pedal and unlocking the bleeder would display a solid stream once bleeding was successful!

[@FordTechMakuloco]

+Cobra Ninety Six With a vacuum bleeder you don't need to worry about bubbles, just suck down a fair amount of fluid into the container and close the bleeder while the bleeder is still sucking.

[@mycosys]

+Cobra Ninety Six if you really want to see use silicon grease (syl-grease) on the nipple connector (not petroleum as it may damage the unit or the braking system - as the oil did his rubber seal) and that should give you an airtight seal.

[@cobraninetysix3883]

Thanks...., I subscribed to your channel. Looking forward to viewing more of your videos, thanks for the reply!

[@liftedjsmith]

I was wondering the same thing. I bought this tool after watching this video, and had so much air coming through the hose, it was hard to tell when the line was bled. Ended up having to finish the job the old fashioned way, while my new bleeder tool mocked me from the sidelines.. Definitely wish I knew about grease on the bleeder threads prior to trying it for the first time! The silicone grease for caliper slide pins should be ok to use you think?

[@chadanderton8059]

@@FordTechMakuloco will this bleed a system that has a new master cylinder that has nit been bench bled?

[@meme5887]

Idk if mine has an issue or what. Just used it today. Worked great removing the old fluid from the reservoir. When I hooked it up to the brake bleed, it was sucking with bubbles (like when you use a straw for a drink but your pretty much empty). And no it wasn't that I had air in the line because when I did it the brake pump way, it came out solid. Switched back to the tool, bubbly. Maybe the lid wasn't tight enough? I'll have to try again this weekend.

[@DefensorFortis]

Threads of bleeder screw letting air in.nise grease around the threads

[@joshg678]

Cool. My 13 escape was low on coolant the other day and i had to add some. not sure if it was a burp from when they replace the Thermostat from the recall or if its leaking.

[@FordTechMakuloco]

joshg678 Most likely a burp as on this one.

[@farmboy30117]

I've used a Mighty Vac with disappointing results. Now I use a method similar to the gravity fed bottle but I push the brake pedal while bleeding. The air/fluid is expelled but since the hose end is submerged in fluid in the bottle, no air can be sucked back in when the pedal is released. Have you seen the tool that injects brake fluid at the caliper to push the air up to the master cylinder?

[@FordTechMakuloco]

farmboy30117 No that sounds hokey you don't want any old fluid from the calipers going back into the abs unit ever.

[@PTucker0864]

@@FordTechMakuloco, What happens when you press the caliper piston back in while fitting new pads? Fluid backs up in the system no? Thanks.

[@craigssellingmine]

Use the Brake Bleeder only with brake fluid. Do not attempt to use the tool to siphon any other liquids. Damage to the internal chamber and seal, or future brake fluid contamination may result. From the instructions

[@FordTechMakuloco]

It works great for both you of course suction the line dry after been doing it for years.

[@saleen308]

[@rickbraden4272]

Thank you. I'm trying to see if this procedure will work on my 2015 F350 to flush the system.

[@CrazyPetez]

I’m bought one of those HF vacuum bleeders the last time I had to replace a caliper on my ‘69 Corvette. Those old 4 piston Corvette brakes are notorious for being hard to bleed, especially the two person method. Using the vacuum bleeder was so easy and clean. The old pressure method still has its adherents, but first you need a special fitting for the oval MC opening, and a way to attach that fitting. The vacuum bleeder is far superior, just remember to keep an eye on the fluid level in the MC.

[@bmwadvice3949]

good video man! i am probably buying this tool ... i am scratching my head as to why anyone uses the pump the pressurize the master cylinder .. this seems much better!

[@stevesisk710]

I have the vacuum exactly like the one you are using. The only problem i have is on my 65 mustang the bleeder fitting is so small that the rubber end piece allows air to enter and can't get a good suction. I am going to have to find and end peice for the hose that fits snug on my bleeder fiting. Ideas?

[@dustinalexander1829]

Will this method work with a pancake compressor? I don't have a large capacity air compressor.

[@justintime8445]

I bought this and noticed that air bubbles were continuously being drawn into the tube. It seems that air was being sucked through the threads on the bleeder screw. I don't think it introduced air into the system, but was curious if you had the same issue?

[@Nordic_Mechanic]

put some thick grease in the bleeder's treads. It'll seal it up good enough :)

[@g8tor68]

Getting ready to do a brake job on my 2011 F150 3.5L ECOboost, mixed reviews on Dot 3 or Dot 4, which one is preferred and how much is it going to take? Thanks

[@mycosys]

+Chad Ross concect a vac hose to the gravity bleeder and bingo.

[@timgiles9413]

Found this video on Harbor Freight. Great review and explanation as to why you should use a vacuum brake bleeder. I'll have to look into getting one of these. Even after I have bleed my brakes the old fashioned way, I still have a spongy pedal. My 2004 Chevy Trailblazer LT 4X4 has ABS brakes. Do I need to be concerned about the ABS? Can I just bleed them; RR, LR, RF, LF pattern? Thanks

[@robbyvanz]

just got this from Harbour Freight. Hooked up my shop air at 90psi. There is zero suction. I even opened the container and put my finger where that large black hole on the lid is, and there is almost no suction. Is this defective?

[@brandonyoung181]

+Robby Vanz it sucks from the hose you attach to the bleeder screw, there is no suction in the container.

[@robbyvanz]

+brandon young I found out what the problem was. The center hole on the bottom of the lid was not punched out during the molding process so the air was not creating a vacuum in the container. I took a punch and removed a small piece of plastic and now it works.

[@MrRexquando]

Great video. Like you I was always budget conscious with specialty tools. What works is what works. This won't help bleed an ABS system if you get air in that though will it? I have always heard you have to "pressure bleed" those.

[@FordTechMakuloco]

MrRexQuando You can use this for bleeding of the entire system including the ABS unit. The only time the abs unit needs special bleeding is when it is brand new you need to do an abs service bleed with the scan tool.

[@MrMustang1973]

I picked up one of these and could not get it to work right. It seemed to be leaking air somewhere. The fluid was not coming out in a uniform stream. Seemed like air was being introduced as it was pulling it out.

[@BlazeIncZeroCool]

I would have returned it and got another. One of the things nobody talks about is how great Harbor Freights return/exchange policy is. Any tool you buy comes with 30 days of no questions asked return/exchange and they are serious about no questions asked. I have had harder times doing warranty exchanges on Kobalt and Craftsman than I ever have with HF

[@scn102]

[@metr0labs]

Just wondering if you can post what vacuum you can pull with that. At 90+ psi with 6.8 scfm compressor I am only pulling 17 Hg. Just wondered how that stacked up to the others who have this tool.

[@flycorvus]

$20 for a kit like this, but you need a shop air compressor for the job. Another $200-300

[@carloscubillo9198]

Excellent video. Thanks a million sir!

[@snowpatrol685]

Brian, u r the man. thanks

[@ThaHandyman1212]

Good video. Do I need to buy a air compressor if so is how many psi do you recommend? Do I need to buy adapters too? I'm trying to take out air from my atv rear brake line. Brake pedal has hardly no pressure. Thanks.

[@mycosys]

+ThaHandyman1212 CFM and capacity are more important than PSI for a shop unit, anything under about 4 cfm is basically utterly useless for shop equipment, even then that is pretty light duty. Light duty 'shop' compressors are quite often only about 3cfm so the bottom end ones may not be ideal. Mine is about 2.5HP, 4 1/4CFM and 10 gallons (they call it medium duty DIY, about 3 rungs from the cheapest shop units) and still reasonably limited - stuff like higher end DA sanders and HVLP spray painting are out of its league - I would not recommend anyone go lower. Mine is also a 'direct drive' unit where the electric motor is in the same unit as the pump - better units are 'belt drive' and can run longer without overheating, wear better and if the do have issues you can just replace the motor or pump.

[@12FlyVA]

I have this product and could not get it to work on my brakes. all is did is such air, would not suck the fluid. I think it was sucking the air around the bleed screw threads. had to resort to the old fashion pump the brakes.

[@MrPaknight]

You gotta put grease around the bleeder threads.

[@robbyvanz]

I find that alot of air gets sucked in past the bleeder screw threads. Is it safe to seal around it with grease or some kind of silicone paste?

[@FordTechMakuloco]

Yes a thick silicone grease like this is what I use- amzn.to/2dlxO8I

[@SerenoOunce]

In place of grease I wrap the bleeders with teflon tape. Has the added benefit of preventing them getting seized years down the road.

[@garyt7830]

Great Idea ….. Teflon Tape

[@dillwiggle2]

I notice they sell some bleeder kits with a 2nd bottle in addition the one your using for filling the master cylinder. Do you use that or your just filling the master cylinder manually by eye ?

[@FordTechMakuloco]

+Dill Wiggle I fill it manually because I don't trust the universal bottle clips to hold it in place for me. If it falls off it's going to be a real mess and it can damage not only the paint but wire harnesses too.

[@sarssars-hm2ox]

I swapping a frame so all lines got opened. I'm doing all 4 corners starting with the furthest. With this type of suction. Is it supposed to take long . Some corners fluid comes out quick and other slow. Am I'm supposed to just do the furthest cause if I keep jumping around am I just moving the air around in the middle of the system?

[@sarssars-hm2ox]

This is the second time doing this type of job but new to brake bleeding kinda I'm always the foot. The brake pedal is getting better but should I stay in one spot or keep jumping around.

[@sarssars-hm2ox]

The first job like this I tried with help but didn't work like regular brake jobs less air in the system. So I used his air suction this time I have the same but newer

[@dcfabrications9152]

What are the specification of your aircompressor? I think my compressor is too small and that the bleeder can't do his job because i haven't enough pressure and air flow

[@ickess]

How about a combo of the first two?

[@broncoviejo78]

Thank you for sharing

[@mycosys]

Nice clear demo. Was that escape a diesel? I seriously hope my mum's little turbo Kuga Titanium (same car) Doesnt sound like that lol - I've yet to see it. Been investigating these units (bugger using the tiny pedal pump one man bleeders for a flush) and on of the tips that has come up a few times btw is using silicon grease to obtain a seal if you want to see whether you are getting air. Otherwise you probably have the clearest vid of the actual unit i have seen.

[@williamdizon5740]

Hello Ford tech, I have a question my 2006 Honda odessey.in the instruction book that came with it when you bleed the brakes you start from the left side driver side, right passenger side and so on.I seen you apply the bleeder only on one brake...

[@FordTechMakuloco]

No this was just a demonstration of the tool. Most cars have you start in the back.

[@Lightningmicro]

Do you recommend one of these on abs cars when the system is completely dry to bleed the system? I used mine on a Hyundai Santa Fe that i put brake lines on and it worked, But i know your suppose to use a scan tool on this car and wondered if i just got lucky or if it always works.

[@gregbrooks9546]

can this be used to get air out of a clutch master cylinder and what CFM do I need with a air compressor.

[@gordylocks]

I got one of these!! Never opened it yet but now i want to! haha!!! Anyhow had a quick question... On my 2012 ford f550 with 6.7Liter diesel it has orange coolant. Can i add dexcool coolant to that or no? Thanks for video!

[@Lightningmicro]

No! hopefully he will answer to confirm but dexcool is GM coolant. Ford came out with a new type of coolant for the 6.7L. Probably the only place you will have much luck finding it and get the right stuff is at the dealer. You do not want to mix any other kind of coolant with it what you have.

[@abdulsughayar4470]

I would like to connect to oil rail ICP sensor what do you think

[@TheJcrandazzo]

Why do you have to follow a sequence when removing the air. Every line is an individual line. Every line is individually sucked or bled of air. What does order or sequence have to do with air bleeding ?? Explain ??

[@bluenadas]

If you're trying to get air out there is an order to follow. The old rule of thumb was rear passenger first but this doesn't always apply now because of abs unit locations.

[@doyleredwine1683]

Totally love your vid. Many thanks for the info. New subscriber now

[@65sohc]

My compressor isn't large enough. Would the hand pump version be as effective? I've been fighting a mushy pedal in a recently acquired 66 Mustang with rear disc brakes. The fronts are fine but I cannot get any pressure to the rear calipers and have bled them a dozen times.

[@FordTechMakuloco]

Pneumatic is the way to go. Have you check the brake hoses?

[@65sohc]

The hoses were old and cracked so I replaced the two at the rear wheels. The one in the center looked OK. I've also replaced master cylinder with a Wilwood and replaced rear calipers. I just ordered a Phoenix Systems reverse bleeder. BTW the rear brakes are from a Lincoln Mark VII.

[@kensteinbach2439]

I got the Phoenix reverse bleeder and pumped about a gallon of fluid from the calipers to the master. If I pump the pedal 3-4 times it gets increasingly firmer, though not normal. After I release within a second it pushes to the floor again. The Phoenix unit also functions as a vacuum bleeder so I tried that. Interestingly when I applied vacuum no fluid would come out of the bleeders. I know there was suction because when I removed the bleeder nipple there was plenty of suction. Any thoughts?

[@agalpalacio9157]

What size gallon compressor would be ideal to use this vacuum brake tool?

[@FordTechMakuloco]

+Angel Galvan ideal would be 30 or higher but a 20 gallon handles it.

[@MRM-wp4gr]

Can this be used on ABS? If so, Do you need to use it with a scanner with an ABS service mode?

[@jpadilla0515]

Does this work for the hydraulic clutch system? My 05 ford focus is being a nightmare not building pressure

[@abdulsughayar4470]

Hi Brian thanks for a great video.. I have a ? for you can I us that tool to prime a 6.0 oil rail instead of cranking the key over

[@aaronbuck7265]

Hey Abdul. Cranking is the worse thing you could do!!! Since you were doing oil rail work I can safely guess you have the oil filter cap off to out a new element inside then the cap as the final step.. You should just disconnect the + starter cable wire on the passenger side firewall and with a new oil filter and cap off, touch the cable to battery + to just crank the motor over with a 10" 3/8 extention or whatever depressing the drain back valve. Once the filter housing fills with oil, quickly put the oil cap on then won't be cranking for days! I do it after every oil change and it fires right up everytime without causing unnecessary wear. Good luck brotha

[@sportster88]

Power bleeders won't work on vehicles with ABS units. My 2001 Dodge truck has to have the ABS unit scanned in order to purge the air out of it. Computerized vehicles suck!

[@PappaTiempo]

You can bleed the caliper and the lines with normal methods...if you get air in the abs valve body, you need to bleed with scan tool.

[@jimmyschmidt14]

I would delete my abs.

[@barryalan4069]

I would like to know how much air presure

[@FordTechMakuloco]

They say 90 psi.

[@kuladeeluxe]

does it make vaccuum via venturi effect?

[@HAHA3035]

Hello. Nice video, I just got this tool and wondering if i need to have break fluid in the "Container" when bleeding?

[@FordTechMakuloco]

No it is all vacuum based

[@HAHA3035]

Ok. Thanks

[@michaelhinchey]

Does harbor freight make a hand pump?

[@artgerhard2192]

Only detail the manual fails to give us is the scfm requirement for this tool. I have one and with 2 hp compressor with 30 gallon tank it just works. I am sure with more HP or more cfm it works better. My guess is it needs 4.5 to 6 scfm to work well. Smaller compressors will not make this tool work. If this is redundant info, delete the post. I appeciate your videos.

Not so cheap tool if you don't have the proper compressor. I wished they worked with 12v ones that you can carry in the car for emergencies.

Gravity bleeding does not work all the time if air trapped in master or abs system

[@FordTechMakuloco]

Yes that is why we vacuum bleed.

[@murdoc4794]

Thanks for this video. I went out and got one of these tools and it works great, but I have a problem I'm hoping you can help with. I have a 2003 Expedition, and regardless of how I bleed the brakes, (2 man, 1 man, vacuum) I get a non-stop stream of air bubbles at both rear calipers. I can flush TONs of fluid through the system, and I always keep the reservoir topped, but I still get bubbles showing up in the bleeding tubing. When I bleed the front calipers, they bleed perfectly. I've checked all of the brake lines and I cannot find any leaks. Have you run across this?

[@johndunsmuir5623]

+George B, I'm not a big fan of vacuum bleeders. They can pull a stream of air in past the bleeder screw threads and out through the bleeder. There is often a rubber washer at the base of the bleeder screw that is supposed to prevent this but I have yet to see one that works. This is especially true if you are drawing fluid through a long thin brake line at the rear of the vehicle. Hope this helps.

[@Fireship1]

Either place a small bead of grease around the outside of the threads to block the air or remove the bleeder screw and seal with Teflon tape and replace. Both methods help with air getting pulled past the threads.

[@chargerchargers7968]
