    EPB Electronic Parking brake question

    On the screw type setups (non cable type)that are built into the rear calipers,and the scan tool says the parking brake has been released, if you heard something and the procedure had actually been successful, should you be able to see that the pistons were retracted back into the rear caliper piston bores, or do the pistons still need to be assisted (pushed or rotated) back into the caliper bores?

    The noise you hear is the force motors retracting the screw drive, but the brake pistons themselves must still be pushed/screwed into the caliper.
