Planning on doing a front and rear brake pad and rotor replacement on a 2019 F60 JCW ALL4 and was wondering if there were any special tricks or tips for the rear pads since it has an electronic parking brake instead of the normal parking brake handle and cable setup.

TIA

 

The factory procedure calls out to disconnect the actuator cable, then everything else is as expected for a normal caliper pad change. The rear piston will need to be screwed in to make space for the new pads, which is common practice for rear calipers. Then, when all buttoned back up. press the pedal down to move the piston into place, and run the parking brake on and off a few times.

 

@njaremka Okay. Thank you for the insight. This will be my first endeavor into working with electronic parking brakes

 

Have you done this rear brake pad change-out yet? Without using a scanner, you take the rear electric brake motor drive off of the caliper, open it up (two screws, maybe 3), then use an torx bit to back off the electric piston. Make the pad change, bolt the motor drive back in place. It's not hard, you just have to know to open it up to back the piston off.

 

Exactly what Mini-Titan said. There are a couple bolts holding the motor on, and it's business as usual other than that.

Remember to turn your parking brake off.

I believe there a setting in the OS for rear pad changes and it will back the motor all the way out for you, but I can't remember if I saw that in Bimmercode or in the onboard system. It's easy enough to back it off by hand once it's disconnected though.

 

This video was helpful even though it's not a Mini.

 

 

Thank you @chrunck and @Mini-Titan for the insight. These videos and the insight that you two have provided definitely help put my mind at ease with the upcoming project

 

I just did this on my '21 JCW with a Foxwell NT710. It has a brake service mode - when activated you can actually hear the electric motor retract. You still have to screw the piston back in, change the pads and/or rotor, and then deactivate service mode when done. Did NOT have to disconnect anything electronics-wise. I believe Bimmercode can get to the brake service mode too.

 

Certainly eliminates the need to retract it manually!

 

I have a Foxwell i53BT and I am having trouble finding how to put the EPB in service mode. Where is it located in the menu? Thanx in advance!

 

Looks like hardware wise the i53BT is an NT710 that connects via a bluetoooth dongle versus serial cable. I don't know if its running the exact same software, though, so please take with a grain of salt.

After connecting to the car, on my NT710 the menu tree is -

3. Special Functions
2. Electric Parking Brake
2. Workshop mode, Automatic Hold brake(Preparing to replace brake pads)

The NT710 then talks to the car and gives a popup saying communication successful, click 'Yes'

Another popup talking about the service , click 'Yes'

This should bring up a menu with three choices -
1. Activate brake service
2. Deactivate brake service
3. End brake service

1 pulls the motors back, 2 re-engages, 3 is for when you're done to get back to the previous menu.

Hope this helps.

 

Thank you!! I will try it when I get home!!
