How to change brake fluid by yourself with a pressure bleeder

[@dhyskRand]

I'm interested in knowing why push the brake pedal when using a pressurized bleeder? I thought the whole point was you didn't have to keep getting in and pump the breaks?

As a series, these are , in my opinion, the highest quality automotive "do it yourself" instructional videos on KZbin. I have attained a level of competence in working on my Porsches I never could have attained. Thank you.

[@RoadandRacetv]

That's so kind of you to say. I'm very flattered you think they are the highest quality videos on KZbin! You've made my day. :-)

[@heluskalove]

Best brake fluid change video ever. Thank you.

[@AdrianWingate2010]

Why are you pumping the brake. Surely the pressure you added (2 bar) will do the job.

[@carlosgraphic]

I'm wondering the same!

[@dinxsy8069]

i was about to comment this, defeats the purpose of using a pressure bleeder 🤣

[@sierra3door4]

There's an O-ring on the underside of the pump handle,I found it best to lube the O-ring. I had a replacement on a different model,and lubed the O-ring to save it from getting damaged

Hello, I have a question regarding usage of this manual bleeder. What happend with the air which is in pipe between bleeder and brake servo tank ?. If you fill the servo tank with fresh fluid and then tight the cap with connector you have a small amount of air under the cap. After connecting the pipe, inside the pipe is air. Then, you start pumping the bleeder and fluid from bleeder is going to the car but before fluid is air which also goes to the servo brake tank. Is it works ? Are you sure that the air is not coming to the brake system of the car. I'm thinking about purchase this type of tool but I have a little bit worries 🙃

I want to know the exact same thing

[@Olav529]

If my logic serves me correctly this will not be any issue, unless the pressure bleeder runs out of fluid. As the brake fluid reservoir/tank is the highest point of the brake system, the air will stay in the tank. Air is lighter than brakefluid which means it will only travel to the top ov the fluid. So logically, the only way for the air to get into the brake lines and rest of the brake system, first the pressure bleeder needs to run dry of brake fluid, and then after that, the brake fluid tank/reservoir will slowly run dry. When the tank runs dry, that is when you’ve got a problem… But this will not be an issue at all if you just make sure to top of the brake fluid in the pressure bleeder and the tank when you see that they are running low on fluid So don’t worry, Just remember to top of the fluid if you aren’t finished bleeding yet, and see you are running low, and you will be all good👍😉

[@efendie3448]

@@Olav529 all what you wrote is right. I forgot about this topic. I purchased this tool and I did brake fluid change. Everything excellent. Air in tank stay always on the top of the tank. It is very easy and fast job. In my BMW F11, I pushed around 400ml by each wheel in about 1h using hand jack for each wheel 😀. Please remeber to use low viscosity brake fluid for cars equipped with minimum ABS.

Hi do you happen to know the the bleed pump adapter to the brake fluid reservoir is the same for a boxster 987 or do I need a different adapter? If so do you happen to know what size do I need? Thanks

[@mortenballe7008]

Excellent tutorial!👍🏼 Thank you!

[@RoadandRacetv]

Glad it was helpful!

[@mattthomasmelmo9268]

10mm socket?

[@beano6584]

Hi I’ve the same lazer unit, can you tell me does your tube go down inside the bleeder to the bottom of it? Mine is brand new but the tube seems to just come off the top of the black cap on the bleeder and not extend down inside it! Bit confused as to how it will transfer fluid like this.

[@RoadandRacetv]

Yours is correct. The pressure forces the fluid up.

[@ssx6867]

do i need to change the oil when the brake fade occurs after exstrem racing ? or is it going to be good after it cool back

[@RoadandRacetv]

+Mohammed Almoslim Change the oil? Do you mean brake fluid? If you mean the fluid then generally yes it will be fine when cool again. Getting it this hot does cause the fluid to wear out more quickly though so it's advised to change the fluid after 3 or so tracks days and more frequently if it's a professional race day. It all depends on how you drive though so if in doubt it's safer to change it more regularly than not. In my experience it's the pads that fade before the fluid boils so it may be worth fitting track pads first. I use EBC Bluestuffs for the track.

[@ssx6867]

+Road and Race yes i mean braake fluid. i just start racing this week and i last 3 laps on the track befor i almost crash on the wall becuse the brake faded

[@RoadandRacetv]

+Mohammed Almoslim Yeah, that happened to me too!. It was the brake pads getting too hot for me. If you've just got normal road pads on try the EBC Bluestuff. Check with your insurer to see if this pad is allowed first though.

[@kostik]

How exactly did you get that filter out? It seems so brutal - I worry that I'll brake something...

[@RoadandRacetv]

Yes, its stubborn alright! Pliers will get it out, just use controlled force and make sure you've put a towel down in case you spill brake fluid on the paintwork. Don't worry about braking it - it's pretty strong and worst case a replacement is cheap.

[@kostik]

Thanks for quick response! Can't wait for more Boxster videos btw.

[@lashlarue7924]

Make shore to dispose ‘uv yon skwiggly-doony alt brake fluid art thon yonder disposal centre at Smugglers Way, matey! Arrrrrrr shiver me timbers, wot wot!!

[@HeidiandFranny]

Great video as always :) I've always just done this with two people, so, with the pressure bleeder, you add fluid there too? We used to have a 987 Boxster S and we would take it to the dealer because I believe you need to tell the computer to open valves (PSM) to flush the entire system. I got this from the Pelican site: "The basic Boxster brake system with anti-lock brakes (ABS 5.3 and 5.7 without PSM) can be bled using traditional methods. For cars with traction control or Porsche Stability Management (PSM), you need to use the Porsche System Tester 2 (PST2) in order to activate the valves in the hydraulic unit during the bleeding process. If your car has a "PSM off" switch on the dashboard, then you will need to go to a shop that has a PST2 so that the brake system can be bled properly." I'm a bit confused about all this so I'll have to do a bit more reading I suppose. I think of this as two steps flushing and then bleeding. I think this is maybe moot for you - I believe you sold your car almost a year ago :( I miss our Boxster... Franny

[@RoadandRacetv]

Big thanks as always Franny. Yes, if you have PSM you need the software. For about £200 you can buy it and the cable so you can do it yourself though. It also does full engine diagnostics. Search for Durametric.

[@rayc1503]

You could bleed the system take it out for a spin to activate the ABS a few times then come back Jack it up and bleed again. Don't forget to bleed the clutch too. Tip top brake bleeding tutorial here great stuff. Just brought the laser 4832 from screwfix and bled my Audi S4 B8.5 brake system. I used VCDS to pulse the ABS system. 👍🏻

[@discountpharmacy5217]

Hi, does the brake bleeder nut need to be torqued ?

[@RoadandRacetv]

+Obiwankadobie There probably is a correct torque figure for it but Indont know what it would be. Also you'd need a special torque wrench. I just tighten it until it's tight then another quarter turn. You don't want to overtighten these.

[@mikemike1352]

Dont you have to bleed clutch since they use same fluid?

[@RoadandRacetv]

Hi Mike. Sorry, I have an automatic so don't know. I guess if they use the same fluid it would be prudent to?

[@marts500]

Great video...btw what make is your brake pressure bleeder & did it come with the correct master cylinder cap/adapter...?

[@RoadandRacetv]

+Eric Gruntfuttock Thanks for the comment! It's made by Laser and I got it from Amazon. All the parts and tools I use are listed here if you need them www.road-and-race.co.uk/tools/ It comes with a standard brake fluid resevoir cap if that's what you mean?

[@TheChannel1978]

Does the Laser pressure bleeder fit the S2000 reservoir cap?

[@rayc1503]

I think you may have to buy an universal adapter. My old Civic had a oval push on cap. Not like the Euro screw cap that comes with this pressure bleeder.
