How to change rear brake pads with electric park brake using no scanner tools 

Would it be wise to disconnect the negative on the battery to make sure the EPB stays in “service mode”?

@@ad8788 yes if you are in any doubt.

hi mate i have a skoda superb and need to change the rear pads. do i HAVE to put it into service mode, or can i just leave the car running, turn the park brake off, then take off the motor and then disconnect the wires then do the work, then do the reverse of it all to put it back on?

No problem. No you don't need to twist the piston. The twist type are on the mechanical handbrake calipers.

No problem. 👍

No problem 👍

Well if you ever find yourself in South Wales then I'll buy you a beer for leaving that comment. Cheers for watching 👍

@@pistonbroke And it'll be much tastier unless Nissan Rogue sources his pints from a micro-brewery. English ale totally pales ours in comparison (accidental pun there). But we do have some spectacular microbrews. Thanks for the video. I can really only say one good thing about electric parking brakes.. there's many parking pawls finally leading a long stressless relaxed long life, with associated auto tranny bits all lasting longer cuz it ceased to mix broken off chunks from time to time from Walmart parking lot bumps. Do you guys have Wal-Mart's? I guess not..but you'll have similar probably. Although you probably have far few bump stops than we do cuz you guys are generally more disciplined and skilled than here. I've given up trying to get friends and family to use the dang parking brake on hills and everywhere to save the tranny. Only 1 ex-girlfriend actually adopted the habit and still does it to this day..bless her soul.. Come to think of it, she still blows the cold off her evaporator 1 minute out before parking too..a fine fine woman. 👍🙏

Who the hell charges three grand to fit brake pads ffs?

Just got told by Mitsubishi a scan tool was definitely needed to do this ... I was thinking there is always a back door....and here it is in the video.....great explanation !!!!

Ok cheers for that. I've never seen a caliper with more than 2 wires.

Hey Kurt! I'm about to do the same on my 2019 3008 SUV, most videos are for the older MPV style 3008 and it seems the EPB is different and you shouldn't use a piston kit alone to push back the piston (as seen on the older car) but you should have it un-done either via the motor's socket or via the method you describe. So essentially, on the newer car, there is no need to really use a piston kit? you can simply push the piston back after it's wound-back with a screwdriver pushing the pad against it?

@@Idontwantausernamist I think you can wind out the back of caliper and then use a caliper tool to push the piston, or do them both at the same time so the piston goes down as you're winding it out on the back? It's been a few months since I did it but what you're suggesting should most likely work. Good luck.

No problem. Thanks for stopping by.

Cheers for watching 👍

I've changed it twice already, I just can't come up with a good name that noone else has already got.

Cheers

No problem 👍

You should on all cars when changing the pads whether it's a mechanical hand brake or not.

I can't remember, T45 I think.

Do you mean the brake pad warning light? If so, you need to replace the wear sensor that goes in the pad. Also check the front brakes.

It's a Renault but these calipers are used on loads of different makes & models. The pads are more than likely different and will depend on what car it is.

Maybe the seal wasn't seated properly and water has got into the motor.

It wasn't a Grandland, it was a Renault something or other, I can't remember! You just need to make sure the park brake is off and stays off while you're doing the job.

@@pistonbroke Everything looks exactly like on my Grandland. Thanks for the video and answer! I live in Cumnock, if there are any problems in our area, write. Good luck!

No, never had that happen.

You just need to make sure the handbrake is off and it stays off.

Don't twist the piston. Do what i did in the video. Take the motor off, squeeze the piston and turn the part at the back of the caliper where the motor goes.

@@pistonbroke what is the name of the tool you used to push it back in?

All cars nowadays are fitted with ABS. I've never undone a bleed nipple to push the pistons back, nor have I heard that it should be done. Sounds like bs to me, if there is contamination in the caliper then it would have already passed through the ABS unit to get to the caliper.

Thanks for the speedy reply. Just found it states to do undo the bleed valve in the Haynes manual.

@@argonaut6386 you don't need to. Haynes also states to replace all brake caliper and master cylinder seals and flexible hoses at certain intervals too.

@@pistonbroke Haynes only copy what is in Vauxhall/ Opel's actual workshop manuals. So if GM say such and such has to be changed at certain mileage then Haynes will say the same. Most of the time they even reproduce the genuine manuals line drawings. They certainly do that on the LandRover manuals I have, along with the genuine LR manual.

What condition are the discs in? If the discs have a wear lip then the pads will need to bed in. You also need to pump the brake before applying the hand brake.

@@pistonbroke new discs and pads all round. I did what you said in the video, pumped the brake before applying the handbrake, all that worked fine it has just left the pedal a little on the soft side. Not sure why

@@tonyhobson9677 they might just want bedding in. Give it a drive and do some gentle braking. I'm assuming the calipers are not siezed, sliders are free and the pads are not tight in the carriers?

@@pistonbroke thanks pal, yes all pins were free and pistons needed little effort to return, I’ll let them run for a week or two and see how they go

Without seeing the car I couldn't tell you what is wrong.

You just have to make sure that the brake will not come on half way through the job. It's unlikely to but you never know.

I didn't count them. I just used what fitted.

Same I think

Release handbrake and turn it off. Some cars will apply the brake again when you turn the ignition off, this is when you'll need to put it in service mode so that it stays off.

No.

No just the back ones that have electric handbrake

Don't need to. Pull the switch and the ECU will wind it out to the correct point. I've done loads this way and never had a problem

Disconnect battery then reconnect if no luck clear fault codes

Yep, piece of cake

The motor either has a torque sensor or a current sensor so the ecu knows when it's on or off regardless of the piston position.

@@pistonbroke Ok, thank you ! I supposed it is something similar, but some mechanics claim that it shouldn't be done without the VAGcom, because it's a risk to block the PKB....

@@robtay1983 Hello Robbie, first you have to excuse my bad english (i'm french 😁), I don't exactly understand your question : in my opinion, as you block your electric brake, your vehicle will be secured ... even when your engine is running ...

@@jansolo55 sorry Didn't mean to add it in your question.

There is a motor on both sides

@@pistonbroke there's a method of retracting the motor by connecting it to the battery, are you aware of this option?

Yes. Quicker to whip the motor off than faff about with wires and a battery

@@pistonbroke fair enough, for me i think it'll be quicker to use wires cos i have many wires hanging around and a jump lead.

@@pistonbroke replaced the rear pads on my 2011 preface lift jaguar xf and there was no motor on it, so don't think all models come with it, though it's electronic to activate in the cabin, it's completely hydraulic at the back end, even better for me.

No idea, never done one. Have a look at the caliper and see if it looks similar to the one in the video. Most manufacurers use similar brake parts.

@@pistonbroke thankyou mate

You've just got to make sure the park brake doesn't come on part way through the job. It's unlikely but it could happen. Did you connect the motors before turning the ignition on? Did you pull the switch before pumping the brake? You need to pump the brake first, then pull the switch and make sure the motors are refitted correctly and connected before turning the ignition on. The car used in this video is a Renault, I forget which model though. I've been doing it this way for years with no problems at all.

I don't know. Most cars use the same type of rear calipers. If the motors look like these ones then yes you can do it.

@@pistonbroke thanks. Done the rear brakes on my 2016 insignia with epb but no motor to remove. I'll get under and have a look

If there is no motor but it has epb then usually the actuator is somwhere under the car and it uses cables to pull the calipers. In this case you would wind the piston back as you would on a normal manual handbrake caliper.

Yep. Make sure it's all plugged back in before turning the ignition on or you'l have fault codes.

Lastly when rewinding caliper back with the t45 torx on the rear . Are you just pushing the caliper from the front? No need for a wind tool?

Yeah, push the piston, don't wind it. You can wind the torx till it stops then squeeze the piston back, you don't need to wind and squeeze at the same time.

Thank you for taking the time to repl. Highly appreciated.

Can't remember exactly. T40 or T45.

Was this ever decided? T40 or T45?

I wouldn't. You need to put it in a service mode to prevent it coming on. Last thing you need is the ecu put the brake on half way through the job.

@@pistonbroke Thanks for reply so still need a diagnostic tool to put into service mode then.

@@robtay1983 no, depends on make and model. For example, with land rover you pump the brake and hold then push the epb switch and hold it for 5 seconds. You could just disconnect the calipers to stop the brake coming on.

@@pistonbroke thank for all your replys got them done today with no probs

@@robtay1983 In this video "putting into the service mode" means disengage the parking brake and make sure it is not on. So no scan/diagnostic tool is needed here.

Then you would replace the caliper.

Get a bigger hammer! Haha

It was a Renault. Can't remember the model.

@@pistonbroke Ok thanks

What's missing? If you still can't do it from this vid then better off getting a pro to do it.

@@pistonbroke job done 👍

Quicker to do it this way than piss about with wires and a battery. Less than a minute to whip the motor off and wind it back with a milwaukee ratchet.

What? If you don't know how to pump the pistons back out then you shouldn't be working on the car. I did say what to do at the end of the video if you care to watch it all.

What a stupid comment Dawn
