How to fully retract rear brembo parking brake?

[copper07]

2017 75 D separate rear brembo barking brake.

I need to fully retract the parking brake to install a new rotor. I was able to get the barking brake off the old rotor but with the piston partially out I know it won’t fit over a new rotor.

Car is in jack mode and tow mode. Everywhere I looked online it says that should do the trick. I tried compressing the piston but that didn’t seem to work.

Any one know how to get the parking brake to fully retract?

You can compress the piston. how are you doing it?

I wasn’t able to get the electric rear brake to compress. I had to remove it from the car. Remove the 3 torx bolts holding the motor to the piston and manually screw the piston back down.

Is there an easier way to accomplish this?
