u/HurryAndTheHarm

Just replaced my brake pads, including the rears. After service, I can no longer engage the EPB at all.

Here is exactly what I did:

1. Engaged EPB maintenance mode. I can confirm I heard the EPB motors whirring for at least 10 seconds after entering this mode.
2. Replaced rear pads.
3. Compressed rear caliper pistons. I did this by turning the piston clockwise and pressing in. I suspect this may be the culprit?
4. Re-seated caliper over pads/rotors and buttoned everything up.
5. Attempted to exit EPB maintenance mode. Whenever I press the parking brake switch, I get an error message saying that action is not accepted. Nothing I do will allow the use of the parking brake switch. I've also attempted the reset procedure per this TSB but it does not fix the issue.

The brake control system warning light is on (NOT the Parking Brake or ABS lights). While driving >25mph, I get a persistent "Parking Brake Applied" warning, but the brakes work and I don't feel any drag or resistance.

Any advice? Did I wreck the EPB or does something need to be recalibrated?
