Electric Parking Brake Forced Release Procedure
WARNING: This page is about a different car, the 2016 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- Perform the electric parking brake forced release if the electric parking brake cannot be released by operating the electric parking brake switch or performing a recovery operation using the ignition switch due to a malfunction in the system or a discharged battery.
- Perform a DTC inspection before performing the electric parking brake forced release, and perform the procedure after verifying the malfunctioning location. (See DTC INSPECTION [ELECTRIC PARKING BRAKE] .)
NOTE:
- The clearance between the disc plate and disc pads is expanded after an electric parking brake forced release, therefore operation of the electric parking brake motor gear unit when the electric parking brake switch is initially operated after the servicing may take longer than normal.
