Hi,

Has anyone replaced the rear brake pads on their 500X? I will be soon. I have the multiecuscan software to wind the handbrake mechanism back (EPB maintenance mode). Do I have to wind the pistons back in once the handbrake has been backed off and the pads are out? After do I just use the multiecuscan to wind the handbrake mechanism on again (Exit EPB maintenance mode)?
Does anyone have any tips for doing the job?
Thanks in advance for any advice.
Nico.

Put brake into maintenance mode
Clean callipers and out new pads in refit them then exit maintenance mode
Should just need to pump pedal a few times afterwards to take up ant slack like normal

Thanks for answering so quickly. I hoped it would be pretty straight forward but didn't want to end up with pistons and brake fluid all over the drive!
Is there no need to wind the pistons back in after removing the old pads?
Thanks again.

Ah yes forgot to put thatpart in
You will still need to wind the pistons back to fit the new pads in they should go in quite easy when the calipers in maintance mode

Thanks again.

Can pads be replaced by manually taking the handbrake off (without multiecuscan software)? And when winding the piston back, just open the brake fluid reservoir as I've done before?

nope as the electric handbrake didn't fully unwind the calipers like letting the cable off would and if you try to force the caliper back you'd likely damage the system

There is an electric motor that is mounted on the caliper and manages the hand brake. On cars with a cable hand brake on discs there is a screw inside the caliper that holds the brake pressure from the hand brake. To force either of these two set ups in without a propper winding tool (or in the case of the electric system the motor winds it back) you wil brake the screw inside the caliper and write off the caliper.

It is ok to force back front calipers but not rear ones with a built in hand brake mechanism.

Exceptions to this are things like GM's drum in disc that has a drum brake inside the disc brake which is used just for the hand brake while the disc caliper is no different to a front caliper in design.

The other problem with electrical systems is the potential for the car to try and apply hand brake while the assembly is in bits which can result in a pretty serious injury if your hands are in there at the time.
