Just a quick video showing how I was able to retract an electronic parking brake on a 2016 Audi Q5. I have been able to use this same method successfully on a few other cars as well.
This is basically just supplying a 12v power source directly to the parking brake motor after the electrical connector is removed. You may have to switch the wires to get it to go the correct direction (Explained in the video). Once the piston starts to spin, you can remove the power supply and use the screwdriver or small pry bar to push the piston all the way in. If you try to pry it in without powering the motor back in first, you will find that it will not move at all.
This is just a quick and easy DIY method that I have been able to use on electronic parking brakes.
Using a scan tool is the 'correct' way to retract the rear electronic parking brake, but I don't have one that has this function.
WARNING
*Attempt this method at your own risk*
*Do not turn on the car with the connector removed.*
*Do not put the power wires on the connector harness that goes to the computer.*
*Step on the brake pedal a few times until it feels firm after you put it all back together which will push the caliper piston back out where it should be before turning on the car. When doing this, don't press the pedal all the way to the floor which can damage the seals in the master cylinder.*

Dan, you're the man. My father and I just used this method to do my wife's 2021 Santa Fe. Thanks for the help!
Thanks for this! Solved my problem with a 2019 Hyundai Santa Fe. When the usual pressing back the caliper didn't work, I tried to disable the EPB, to no avail. Watched several other Santa Fe-specific videos that didn't include this vital info. You got me back on track to a successful brake job.
Thank you so much! I was trying to juggle my kids and press the piston back to no avail. Even broke a screwdriver haha! So thankful for all of your help👩🏼🔧🔧
2018 Traverse 4WD
I appreciate you for this video, it was my first rear brake change with EBS
Great knowledge buddy 🥳
Been doing this for years on lots of cars. Once new pads are fitted i just plug everything back in, pump the brakes a few times and operate the parking brake again. No error codes have ever come up for me..
If you can get a pair of leads, you can get a fuseholder too and put it close to the battery. Even if you know what you're doing, things can go wrong.
Great video, thanks!
Great video. Used 12v power tools but Milwaukee and Rigid 18v work great too. You can run many accessories specially power seats at the junkyard etc.
thanks for video. very clear instructions. I appreciate that.
Best video I’ve ever seen😊
Great video very simlpe Thank you save a lot of work
This worked on my 15 Macan and 12 A6 perfectly
Thank you, this got me out of a pickle with my 2017 Mercedes 👍
Thank you for this helpful video.
I was wondering if bmw electronic brakes
have also 2 prongs.
If you put your car in drive to trick the PCM does that work? Any suggestions?
Thank you share clip
Do i disengage the parking brake first?
Thanks for this video. I should have watched this video before trying to change the brakes on my 2019 Lexus UX200. I’ve watched the service mode tutorial video but it didn’t work instead it pushed the piston out. I made a mistake of taking the caliper out before retracting the piston. When I tried screwing back the piston in, I stripped the thread on the bolt and nut that pushes the piston out. I can’t find that part anywhere so I had to buy a new caliper. I hope I can find that part so I can rebuild the ruined caliper.
So if you had them wrong will it come out instead of in?
Do you then reverse the process once the pads are in to reset, or will the system automatically reset at startup?
No, but after you complete the brake job and have everything back together, Before you start the vehicle, press the brake pedal about 1/2 way down a few times until it feels firm and then when you start the engine and apply the parking brake It will automatically adjust to where it needs to be.
Thanks for watching.
If the parking brake activated while you were doing one side. Will it still work for the other side? Or do I have to buy a new motor?
After performing this, now the Corolla is giving a parking brake malfunction code on the dash. The brakes seem to function normality but the parking brake will no longer engage. Any suggestions?
Do you have to do anything to reset the EPB when all is done? Also is there a EPB on the front Q5 brakes?
I didn’t have to reset it or anything like that. It’s working great.
Thx for watching!
-Dan the Fix it Man
And there is not an EPB on the front, only the back
Hi, My EPB on rear left caliper is not engaging and I am going to replace the actuator. I guess I don't need to retract the piston or something like that right? as the parking brake is not activated so can I simply replace the actuator without any retraction and scan tool?
You should be able to remove the caliper with the mechanism and motor without having to retract anything unless the mechanism/motor is stuck on (parking brake applied), then you would have to take off the actuator motor (two allen head bolts usually) and manually turn the mechanism in. If you are changing the motor only and are going to re-use the caliper mechanism, then you will still need to turn it back in and press in the piston before putting it back together. Hope that helps!
Thanks for watching!

This technic work in Q3 2021?
Would the caliper not already be rewound if you just released the brake. Or will putting the battery on it rewind the piston back a bit more. ?
When the parking brake is released, it is not far enough back to fit the new pads in.
@@DantheFixitMan i wonder if you apply pressure , would that activate the parking brake release again ?
The parking brake actuator only rewinds a little when you release the parking brake, just enough to allow the square cut seal to pull the piston back in a little, and just enough move the pads off the disc, just like any normal calliper without EPB would do.
To change pads you need to wind the actuator all the way back, so that you can them push or press the piston all the way back following that.
The method shown here is one of a few if you don't have a scan tool or diagnostics phone app, but isn't a method I would recommend however, as damage can be done to the actuator by applying power to it like that.
Scan tools and phone apps don't cost too much, which are capable of fully rewinding the parking brake mechanism and stopping properly when resistance is met.
What about once you're done? Do you do that to close the break back up? Or do you just push that electronic break in the front seat?
Just push the button to apply the brake and it Will automatically adjust.
Thanks
So we were doing my rear breaks on 2018 gmc terrain. We did not disconnect the wire. Had the door open and a kid had accidentally pushed the parking break button while the caliper was off. The piston pushed all the way off and then fell out. Brake fluid leaked. My question is if i turn the car on without turning on ignition is it okay if i push the button again to release the parking break or will that make things worse?
You need to re-install the piston and bleed your brakes because now you have air inside the braking system, add brake oil to the required level.
the kid who was helping you do the brake job should have told you what to do.
Can you use your own car battery to retract the piston?
Yes
Will this work for a 2014 Mercedes cla 250 without giving error codes when I disconnect it.
I have never had a problem with this method as long as the car is turned off. Do this at your own risk.
Disconnect immediately when you hear the noise of the motor change. The author did this in the video, but the point warrants emphasis. The change of the noise indicates that the motor has reached runout. At runout, where the motor encounters mechanical resistance, a current spike naturally occurs. In normal operation, the controller senses this current spike almost instantaneously, and responds by cutting power to the motor. In other words, the controller knows to turn off power to the motor when it sees that current spike. Since you're a human, you can't react instantaneously. If you leave a light-gauge wire connected, with all that current, you will heat the wire quickly, and burn the insulation. When you think you are nearing runout, switch to quickly tapping to make the connection. When you hear the noise from the motor change, the piston is fully retracted. Stop tapping.
Would this not throw a code though?
Would you recommend using the battery in your vehicle for this???
Because if not then I'm not buying an entire new battery to do this lik
Yes, you can if you have jumpers long enough, or if you want to remove your battery to do this, but I definitely wouldn't buy a new battery just for this method...
I have also heard that even a small 9volt battery will work although it might go slower... Best of luck to you!
Thanks for watching!
-Dan the Fix it Man
@@DantheFixitMan thanks a million, 9 volt it is lol
@@MOAON_AABE No problem, please let me know how it goes.
Thx!
I did this and now have a electronic parking brake malfunction light, do you have a solution for this?
Hi Luke,
So sorry you are having trouble with this. I have never had a code show up after doing this as long as you keep the car off and don’t turn it on until you are done. You might need to have the code cleared with a scan tool, or you may be able to clear the code by temporarily disconnecting the battery ground cable.
I've done it with a 9v battery. Motor runs slower, but it works.
That's really good to know for next time thanks!
Thanks man, I just used a 9v to do mine
No shit? Just a simple 9 volt will make it work?
I don't need a car battery like this guy???
@@MOAON_AABE Nope, Just make sure it is a new or fairly good 9volt battery.
Why dont you switch car off with Parking brake off or do not engage it. I keep forgetting on my Audi Q3.
Great question,
From what I understand, that doesn’t retract the parking brake far enough to fit the new pads in.
Thanks for watching!
-Dan the Fix it Man
Only on newer vehicles with electric parking brake. Most vehicles still use a drum style parking brake on the rear disc brake
Such a shame that so many people can't spell Brakes when relative to Vehicles. Break is when you stop for coffee and a KitKat.
First off, i want to say what you do and your videos are good, I'm not trying to sound like a hater. And I know you're trying to do it cheaply for others but it would also be a good idea to teach them how to do it with the proper equipment/tools.
You could just do it properly by putting it into service mode with a scanner. Obviously this method "works" and saves you $75-100 on a scanner, that you'll only use once or twice a year. However, you can still damage that piston using this method. Which if it happens to you, it could end up costing you several hundred dollars depending on your resources. Personally I wouldn't cheap out nor risk it over a $100 scanner.
* I own a mobile brake and rotor business and I have had a couple of customers who had someone else come do it, which Im assuming was a buddy, and ended up damaging it. It's easy money for me as with that same scanner I bleed out the system after replacing the caliper. But to each their own.
It's all good Christian, I appreciate the feedback. I do have scanners for several vehicles, but did not have anything that was compatible with the Audi at the time I made this video.
Happy wrenching!
Take care,
-Dan the Fix it Man
I would love to pick your brain regarding Mobil brake and rotor service as I’ve been thinking long and hard about executing something like that.
@@joshuarose3081 No worries, my email is listed under my contact info if you want to shoot me a private email. Otherwise, feel free to reach out to me here...or, I guess you might have been wanting to reach out to christian...either way, I would be happy to help.
Take care,
-Dan the Fix it Man
@@joshuarose3081 go for it man, seriously. Don't overthink it; that's the biggest obstacle. A lot of people think and think but never do it out of fear. There is a lot of money in it, and I think it's easy work. But it's just that work, something people don't know how to or plainly don't want to do. For something that requires a few tools, and basic knowledge it's a good side or eventually full time money generator. It's something people will always need. For example I never sell anything else but where I make even more money is in rotors. Rotos along with pads as a package is where there is even bigger money. Idk who your comment was directed at but if it was also for me, hit me up with questions.
@@DantheFixitMan Dan thanks. I was looking into starting small in my area with a mobile brake and tuneup service but have no idea what goes into it. I’m basically just doing some homework at this point. I’ve been doing brakes in my driveway for family and friends for the better part of 25 years so I’ve got some experience and a ton of tools. I’m 45 and tired of working for other people at this point in my life.
You don't need to do any thing you did you can use a regular wind back tool that turns the piston as you retract it and that will turn the screw that holds back the piston as well
Takes forever
