So my rear brakes are due here shortly and I always thought because of the electronic e-brake control I was out of luck with the Dealer having to do this. after watching quite a few YouTube videos tell me I understand this correctly but it seems like this can be bypass without using a computer to retract the piston by disassembling the motor and than using a T45 torx and retract the piston back in replace using a caliper retracting clamp am I correct on this could I can do this myself if that's the case!
