2010-2015 Toyota Prius Brake flush

[@lynxonwatch]

Thank you for all your Prius videos, I've just finished the 2-yearly service replacing coolants, oil and brake fluid. I used the Techstream tool to bleed the brakes, I'd like to share a few notes on that: First, make sure your auxiliary 12V battery is fully charged. Even better, connect a second 12V battery or DC power supply in parallel to it (plus on plus, minus on minus), since it might take a while until you're finished, and during that time, the Prius is ignition-on, ready-off. My 12V was stone dead after the procedure (down to 6V). The sequence of bleeding with Techstream is RR, RL, FL, FR. So you can jack up one axle after the other, no need to go diagonally. The Techstream app tells you exactly what to do, the app can be found in the ABS/ESP/VDC menu under utilities-Air bleeding. The connector for the reservoir level is right next to the reservoir. Its status can be checked in the data section of the ABS/ESP/VSC menu. The rear brakes bleed by themselves, having pushed down the brake pedal (I used a stick between front seat and pedal) just by opening the bleeder valve. The front brakes require pumping of the brake pedal (needs an assistant). I suggest you use a small glass jar to collect the fluid in small quantities, to check the colour until it comes out clean. Check the reservoir level after every brake bled. Have a decent supply of brake fluid at hand. Close the brake bleeding screws when the liquid comes out. Use a brake line or ring spanner for the bleeding valves, since these are quite small and might slip if stuck. My brakes are now crisp and sharp like never before!

[@pgreenx]

What is the tech stream tool? thanks

[@lynxonwatch]

@@pgreenx Techstream is Toyota's diagnostic software package.

[@spankrobot]

techstream has to be rented ("subscription") and you need an interface connection between laptop and OBD port

[@alaind831]

good point about connecting a 12v power supply. Completely killed my battery this time (last time was 3y ago) and freaked out when I got an ABS error code (which I cleared) and the car would not go into D mode and dashboard would sometime not come on... I thought the reset tool I used killed the car until I realized the dome lights were very dim and was likely a battery drain issue. Jump started the car back to life! drove it around for a few days and had battery tested, it was down to 160CCA (half) and something like 11.8v so time to change that 8.3y old original battery with 185k - they are expensive! could have probably used it a few more years if I never connected an ODB tool to run test on it (it died a second time doing a short test, so yeah time to replace battery).

[@alaind831]

@@spankrobot ​ @LynxWatch techstream - I may have to look into it as I have error codes C1203, C1345 (linear Solenoid Valve Offset Learning undone), C1392 (zero point calibration of Stroke Sensor undone) I cannot reset. I have a foxwell NT510E Toyota and I asked them about getting *ABS -> ECB Invalid* to work *thinking this would be the same 'invalid mode' used here* without doing 30+ steps, and they sent me a working patch, but instead I got 2 ABS errors I cannot reset (mentioned above) and no blinking ABS light that gets reset on OFF/ON... they told me to do 1) Special function -> *Air bleeding* (which I didn't rally need as I have no air, but it worked the pump) 2) ECB Utility -> *Reset Memory* (not clear that worked) 3) ECB Utility -> *Linear Valve Offset* (didn't seem to work as I never got ABS/Brake light flashing at different speeds) 4) Special Functions -> *Test Mode* to reset the code but they are still there. Now I have a 2014 Prius with no ABS, no regenerating braking, and no power braking for that matter! bunch of lights on the dashboard... last thing I want to do is pay stealer to reset this all but foxwell is slow to respond (24h china return email) and running out of patience. It's all their fault too - their invalid mode isn't the same (not sure why on earth one would use "ECB invalid" if that what it does) and the above step 3 doesn't work either...! Q: can you use "Standard" $20 or do you need "Professional" $65 to reset the linear Solenoid Valve Offset and erase those ABS codes ? @NutzAboutBolts do you have it and can I come over (I believe you're in the bay area :)

[@likeathinkpad]

You’re the best. Thanks for helping out the community. I just bleed my prius 2014 braking system following the same procedure after I discovered a leak in my front driver caliber due to loose banjo bolt. It works like magic. Please do more videos about prius, i love it.

[@bobweck1317]

Thank you, buddy. Really appreciate the tutorial video. I've been disabled from being able to work, so money is a little tight; therefore, I need to do as much service on my vehicles as I can do to save money from the prices the shop wants to charge. Much thanks. You 'da bomb! 👍

[@fyop1987]

I can not thank you enough for this. I had to change the caliper on my 2013 Prius and had no idea what was involved in bleeding the brakes until I googled it. After having a panic attack I came across your video and it was perfect. Thanks again !

[@Adreiaun]

This was very helpful. Tried for a half a day by myself to no avail. Got it done in less than 1/2hr after watching this.

[@PlnJn]

Likewise, thanks for this video. BTW, a pump is not necessary for this procedure. I bought a manual pump from Harbor Freight, and I used it to drain the reservoir. But honestly, it wasn't necessary. I could've just drained it all out the first rear brake line. And to do that, I just pressed on the brake pedal for 10 seconds at a time till I was satisfied that the fluid coming out was clear. Another thing - the front bleeder screws are 8mm, not 10mm like the back ones. Oh, and the front ones suck a lot of fluid out of the reservoir, so I suggest pumping the foot brake 5 times then checking the clarity of the fluid & the drain out of the reservoir.

[@robertmontgomery7158]

Success! I was able to get into invalid mode and successfully bled the brakes!! Great videos!!

[@typhoon320i]

Just did this. Thanks for the walkthrough. It was hard to keep brake fluid off my newly painted calipers while doing it.

[@NutzAboutBolts]

It’s ok, just brake clean the fluid away and you’ll be fine.

[@treborg777]

I tried bleeding my 2010 Prius brakes with these instructions and nearly completely drained my 12 V battery. I was doing one wheel at a time (wheel off, bleed, wheel on). I'd recommend that a 12V battery charger is connected to the 12 V battery in the back of a Prius before starting this if one doesn't take all the wheels off first.

[@skorpyo331]

treborg777 maybe having the key fob near the car helped that?

[@Jatsotserah]

Probably not Skorpyo. That mode is accessory so it's understandable to have battery drain.

[@Juss-Saiyan]

PLEASE can ANYONE tell me how the scan tool method is any better? OR is it any different at all?

[@NutzAboutBolts]

@@Juss-Saiyan the techstream scan tool uses a laptop to activate the brake system to bleed the brake fluids as opposed to doing it manually by doing the invalid mode. Of course doing the techstream way is easier but if you don’t have it, this method works as well.

[@minalimadhara4755]

I got abs check lights on after 8sec holding brakes but cleared the codes using paper clip method works normal now ? Is that ok.?

[@arvindersingh9891]

Nice video! I don't have a vacuum pump. I was wondering what is the alternative.

[@NutzAboutBolts]

Just stick a plastic clear tube on there and it should be fine

[@br31woodlands69]

Can you do this by disconnecting 12V so you don’t have to put in invalid mode?

[@NutzAboutBolts]

No, you need the vehicle running to put it into invalid mode. You’ll need it running to flush the brakes as well.

[@user-pf8jj1uu1f]

Is the main difference between the rear and front brakes that the pedal goes all the way down, so you have to close the bleeder and pump the pedal again? And when doing the rear brakes, the pedal stays firm, so there's no need to pump? Also, what does putting the car in brake mode actually do?

[@Drive4YourLifeAZ]

Does anyone know if this will help with abs /brake safety code on dash board? Do brakes need bleeding if they appear to work great?

[@djzorch]

I doubt it tbh. I'm no expert but it could be a bad sensor

[@brlearning1351]

So Toyota Prius 2004-2009 same doing like this?

[@NutzAboutBolts]

I’m not sure since I haven’t worked on a 2nd gen before, but gen 3 and up seems to work this way, unless it’s an all wheel drive vehicle.

[@rj.parker]

Toyota warns: Do not depress the brake pedal to operate the brake booster pump more than 100 seconds at a time. When performing the procedure continuously, release the brake pedal to stop the brake booster pump operating and depress the brake pedal again. Otherwise the system will set codes and disable invalid mode. Invalid Mode Procedure: Engage parking brake Power Button twice Press brake and go into Neutral Press brake x8 in 5 secs Press Park Press brake x8 in 5 secs Press brake and go into Neutral Press brake x8 in 5 secs Press Park and note Blinking brake light (yellow circle with exclamation mark) You are in invalid mode Bleed rear brakes by holding pedal down Bleed front brakes by pumping brakes Power down to exit invalid mode Consider using charger on 12v battery

[@willyag2529]

It's great to have it written down along with the video! Connecting a battery charger Is a good "just in case" suggestion.

Many thanks NutzAboutBolts! Just did the brake fluid change today; your video helped immeasurably.

[@NutzAboutBolts]

nice! glad you were able to do it with confidence :)

[@dmo9984]

Thank you for the clear and concise video! Mushy brakes after changing rear caliper on 2011 Prius. Took about an hour and now it stops like new again. I rotated the rear wheel prior to moving to the front brakes and it canceled invalid mode just as you said. Why didn't it throw any errors when I opened the front bleeder screws or pumped the brakes?

[@NutzAboutBolts]

Because that mode is only meant to service your brake fluids.

[@rspaulding]

The manual says to start in the RF, then LF, LR, RR. But you start in the rear?

[@agentstona]

Hey nuts and bilts i really need your advice ..when i press on my brake peddle all the way down while parked it makes a sucking noise ... plus the break pedal fights back and pushes back up ... i have the abs lights on and a beeping warning sound when i turn the car on but when i shift to drive the beeping aound goes away and the break becomes soft again but the abs lights remain on ....what could be the issue do you think its the ABS booster valve ? Does the front breaks need bleeding ? Or need replacement of the booster

[@robertmontgomery7158]

I have a 2015 and the procedure to get into invalid mode does not work. Very sad. Love your videos!!!! Keep them coming!

[@NutzAboutBolts]

thats interesting since they're all 3rd generation Prius...

[@robertmontgomery7158]

NutzAboutBolts I agree. I never get the flashing brake light.

[@robertmontgomery7158]

NutzAboutBolts Do you think the rear brake line would drain by gravity? And what would happen if you just pumped the pedal ?

[@NutzAboutBolts]

no, the rear brakes are electronically controlled, its way easier than the fronts. The fronts are hydraulically controlled, so you will have to pump the brake pedal and hold. The rear's you can just hold on the brake pedal and open the bleeder valve and it'll start draining out.

[@geeshepherd9080]

Robert, make sure the parking brake is on. Mine wasn't working as well until I pushed in the parking break. It's a pedal on the left side of the car near the door. Push it down with your foot and try the method again.

[@mikewong5888]

Highly recommend you buy a pressure bleeder to ensure a clean flush and no air bubbles. Well worth it.

[@GodzillaMX007]

Can the rear breaks be bleed like the front ones if no vacuum bleeder is available?

[@Viper3870750]

Hey I know you've asked this 2yrs ago, but did you ever find an answer to this? I'm needing to bleed my brakes this week as well.

[@rockervdrive]

Nice tutorial! Would it be possible to use the vacuum machine bleed method for the fronts, if no one was around to pump and hold the brake pedal?

[@NutzAboutBolts]

no since the front's are conventional braking. I would ask someone to pump it for you.

[@how-toswithmark902]

Hey bro can you do this to fix the light on after changing the booster pump and brake actuator??

[@feedingthehungry8489]

can you please do a brake actuator video

[@terrytorres7075]

Help! We changed rear breakers. We bled them by pumping pedal. The battery was connected. New calipers and rotors and pads. Now I hear a hissing like when I press brake to start car and a weird noise when I shut car off. And" maintenance car soon" light comes on quick. What should I do????

[@NutzAboutBolts]

Is it hissing or buzzing when you step on the brakes? Any check engine light? Maintenance car soon sounds like an oil change reset light is on.

[@SquirrelsForAll]

Thank you for your wonderfully informative videos, They've helped me tremendously in servicing our 2013 Prius V. Thanks!

[@EsenbekAliev_]

I know it was 5 years ago, I'm doing bleeding tomorrow, what was the issue?

[@experiential]

Was just helping a friend do this job and the same thing happened. Did anyone figure out what to do? ….not a good situation to be in.

[@EsenbekAliev_]

@@experiential we did it last weekend and all went well, just never turn rotors or open doors. While in invalid mode. You have to tow your prius to toyota so they can clear errors.

[@prabhusoundappan8662]

Thanks for your videos. I was able to change the PCV value without any hiccups. On the Brake Bleed video, can I flush the rear brakes the old school way(by pumping) without the bleeder suction pump?

[@NutzAboutBolts]

no, the rear brakes are electronically controlled, there is no pumping action needed, just step on the brake pedal and the brake fluids will start flowing out.

[@GodzillaMX007]

So the rear bleeding, instead on pumping the traditional way all you do is press once and fluid starts coming out until depressed? I guess like you mention its like a switch once you press it the fluid automatically starts flowing out (rear breaks)

[@mrraghan73]

Thanks your video's ..same procedure for 2006 Toyota Highlander Hybrid model air bleed out ? Thanks

[@nicholassurr5789]

I have a 2012 lexus ct200h. Is this the same procedure?

[@rhys5483]

I've seen multiple queries about why the need to put the car in "invalid" mode, but no answers. What happens if I bleed the brakes the old fashioned way, w/out putting the car into invalid mode?

[@NutzAboutBolts]

Rhys you can bleed the front brakes conventionally, but the rear brakes are electronically controlled, so if you try to bleed it without putting it into invalid mode, it won’t work, and you’ll be introducing air into the system, which can cause a check engine light.

[@kumara5492]

I could not get my toyota prius v 2012 into invalid mode following this way. I think there's different way to get Prius v into invalid mode.

[@jamespb20]

Were you able to figure out how to put prius v into invalid mode?

[@at8277]

This might bea dumb question. With this procedure, abs fuse does not need to be pulled right?

[@NutzAboutBolts]

No, you don’t need to.

[@ericastanton2010]

what if you do not put in invalid mode. i saw a video that all you need to do is open bleeder nut and press on the brake and the abs system will pump out the fluid.

[@NutzAboutBolts]

Have at it and let me know. This is straight from the service manual.

[@sashaviroviy5065]

So did you use “Invalid mode”? How is outcome?

[@skorpyo331]

Big question now, will I be able to perform this after a new diy install of a new master cylinder and booster and then filling resevoir and then reconnecting battery??

[@NutzAboutBolts]

Haven’t tried that, so can’t say, but most likely you’ll need to bleed the fluids, so why not try it 🤣 let me know how it goes.

[@omidrostami87]

So when I put the car on N and do the pump for 8 x and then ones I click the P the car comes on! And by following all the steps nothing happening I think by car coming on it cancels the procedure

[@tylertran93nsx]

So you don’t need a scanner? Can this procedure be done after replacing the ABS module and brake booster?

[@GrandPrix46]

Won't hurt to try. I had a C1391 for about a year, and I recently lost my brakes (C1252, C1253, C1256 very stiff pedal hardly stopping the car) and will probably be replacing the actuator and accumulator soon. The previous owner replaced the actuator at 215k in January 2023, car has 251k now, so I'm not sure if he didn't bleed it properly after replacing the actuator. It shouldn't be bad after such a short time/few miles. I'll probably try this bleed procedure first and see if the pump stops running every 7 seconds, if no change I'll order the parts, replace, and use this procedure to bleed it. If this bleed procedure doesn't work, I'll probably just have the dealer do the bleeding with their software. Not sure if I want to play around with techstream trying to get that to work on my laptop.

[@kevinchan2781]

Thank you guys for making this video! Very helpful and straightforward.

[@TerjeNormann]

[@Ayyubi12]

Hi I m in trouble and dont know how to proceed. I followed your instuctions and put the car in invalid mode. Yellow exclamation mark began blinking. After when I wanted to disable invalid mode I did wrong and depressed brake pedal and pushed power button instead of only press power button. Now I have abs, traction, yellow exclamation lights and pedal goes to floor. Also red exclamation light also lights. Do you or anyone else know the problem?

[@sayman83sayman83]

What about the Toyota Rav4 Hybrid 2016, is it working also like this?

[@NutzAboutBolts]

You can try, most hybrids do the same procedure, unless it’s an AWD.

[@sphericalsphere]

Did it work? I have one too

[@rondhole]

I would check the water contain first with 2 probe sensor for $10 in amazon, if it is still good, i would not flush the whole system. Toyota brake system is not prone to contamination, many trucks owner never do such service for 20 or 30 years even with ABS as long as the car never been in accident or flooded.

[@DrDaddy-yg2ki]

Will this chicken dance and procedure wok for a 2013 prius C???

[@numberformat]

The brake bleeder pump and hose is expensive and will not get much use since brake fluid gets changed so infrequently on this car. Is there something else I can use instead?

[@NutzAboutBolts]

you can just use the hose, you don't need the vacuum bleeder.

[@brandoncser2842]

Should the key be kept away from the car when performing the bleed procedure in invalid mode? Is opening the door okay when in invalid mode?

[@sti6264]

I haven't done this yet, but judging from the video, the car needs to be on to be in invalid mode. And to turn the car on, you need the key. So I'm guessing no, the key doesn't need to be kept away

[@Boodieman72]

Why do you need to put it in invalid mode?

[@ngkm2]

Hi, I'm planning to replace my front brakes on my 2010 prius. Do I need to put it in the "invalid mode" to compress the calipers pistons? I heard some horror stories about people compressing the calipers or having the key near the car. Some hydraulic solenoid is energized and prevent fluid from coming out or something like that. Any advise is much appreciated. Thanks

[@NutzAboutBolts]

people changed their brakes when the vehicle is turned off. Make sure your doors are not open and keys not around to accidentally activate the vehicle. If you open your driver door, it will activate the ABS system and can cause the caliper piston to depress and it'll be a pain in the ass to put that piston back into the caliper. So make sure not to activate the ABS while doing the brake job.

[@ngkm2]

+NutzAboutBolts Awesome! Thanks for the quick reply. Have a good night. I'm here in SoCal.

[@NutzAboutBolts]

nice, there's plenty of forum threads on PriusChat if you're still nervous. There's quite a few that did their brakes already. Make sure to flush your brakes once you're done with the brake job if the brake pedal feels squishy.

@@NutzAboutBolts yes, it already died on me as I was doing a Techstream scan of the car systems for 10 minutes or so with the car in accesories mode (not Ready). But I charged it and it works fine for now. However, it is rather small capacity and with the brake booster and electric mirrors, DLRs and all it doesn't get to charge fully, as I'm doing mostly short trips. Thanks for the reply.

[@NutzAboutBolts]

@@RaduLazau yeah, I’d say just replace it since it’s not holding a good charge. Battery voltage should be 12.6volts. But if you still wanna keep it till it dies, I don’t blame you since these battery costs 200+ lol

[@joeshmoe8952]

How often should this job be done?

[@NutzAboutBolts]

Whenever it’s dirty or every 90k or so.

Thanks for taking the time to make this video and helping people out! You made it clear and simple. Could you direct me where did you buy your vacuum brake bleeder, thanks again.

[@NutzAboutBolts]

+Nero Nguyen I bought it at MatcoTools, its called MityVac brake bleeder model MV6830

[@drummerrck]

Prius isn't going into invalid mode. Reservoir full. Any suggestions???

[@NutzAboutBolts]

What Prius model? It should work on the prius…

[@drummerrck]

@NutzAboutBolts I got it to work. Had to try it a bunch of times and still not sure what I did differently. Maybe a bit faster. It's a 2012 prius II

[@NutzAboutBolts]

@@drummerrck nice work! yes, the steps are time sensitive, that's why they only give you 5 seconds to do each step or else it won't work. Glad it worked out for you.

[@anthonysobczak2723]

My question is: Why are we putting in new fluid before we bleed/flush the valve? I don't want to be flushing away new fluid. Can I flush/bleed the old fluid then put in the new fluid?

[@NutzAboutBolts]

We suctioned the reservoir of the old fluids, then refill with new fluids. Whatever fluids were in the brake lines are old, so when we did the flush, it’s pushing out the old fluids and the new fluids are taking over the lines. Hope that made sense. Also, you don’t want to run the reservoir dry or else it’ll damage the brake components.

[@anthonysobczak2723]

@@NutzAboutBolts that makes sense. My concern is with flushing away new fluid, I will be cautious with how much I Iet out of the valve

[@NutzAboutBolts]

@@anthonysobczak2723 1 bottle of brake fluid is cheap and should be enough to flush the car. I have so much unused brake fluids because it doesn’t take much to fill up the reservoir and flushing it 😆

[@K_S536]

How many small bottles do you. need to flush out all four brakes?

[@NutzAboutBolts]

Two 1 quart bottle should be enough

[@raytwal1]

I did everything like you said. But I at the end, I got the E brake light and ABS light and the traction light On. Where did I go wrong?

How didn't you bleed the brake system?

Where do you think I can get the instructions on how to bleed the 07 Camry hybrid?

[@NutzAboutBolts]

maybe you have to buy those pdf files on ebay.

[@8peterp]

I got Mini VCI cable and installed Techstream ,has air bleeding utility. was very cheap

[@jonathanbreaksit]

Does this work for 2005 2nd gen also?

[@LoveLikeaHurricane]

....poor timing of brake pump and bleed on the fronts?

[@NutzAboutBolts]

?

[@hedgehogthesonic3181]

Can invalid mode be used to bleed the brakes decently?

[@NutzAboutBolts]

Yep

[@kaltrex9465]

Do you need to flush it? What if you just kept adding new fluid to the M point?

[@NutzAboutBolts]

Yes you’ll need to flush it, adding fluids to it won’t help because when your brake pads wear down, the fluid drops because it’s compensating for the loss of the brake pads, when you put new brake pads in, the fluids will go back to the full mark.

[@sungn4512]

great stuff thanks for taking the time in putting this together

[@friedhelmaugstein8706]

Can you please let me know what gscan model you are using, and will this work with my second gen 2008 Prius?

[@NutzAboutBolts]

We didn’t use any scan tool. Not sure if this method works on the 2nd generation Prius.

[@dnham314]

Does this work for a 2015 Prius C?

[@hamzam.9815]

Just did this. My 2012 Prius ABS accumulator was running quite often. Every 32 seconds WITHOUT pressing the pedal. With pedal press, it ran on every 3rd pedal press. I did all this and now the accumulator pump never runs until I press the pedal. And on every 3rd pedal to be precise. Fingers crossed, people said wait a couple of weeks if it returns, I’d have to change the whole ABS unit.

[@CCG0D]

It seems like your suspicion alligns with mine. It's been 9 months so, is your ABS okay now? I hope you fixed it by flushing the break fluid like this video.

[@hamzam.9815]

@@CCG0D After a month it was back. I ended up buying a new accumulator and the actuator

[@jdmfans6078]

What if I don't have the vacuum? 🤔

[@NutzAboutBolts]

For the rear, just open it up after your partner step on the brake pedal, it’s electronically controlled so you won’t fear of air getting in as long as he keeps the brake pedal depressed and you open and close before the brake fluid reservoir goes empty. As for the front, just open and close right away after the 3 brake pedal pump. Hope that helps.

[@jdmfans6078]

that means . i don't need fancy scannner to do the job?

[@NutzAboutBolts]

Nope

Is it the same for 2018 Prius?
