Disc Pad (Rear) Replacement: Notes

WARNING: This page is about a different car, the 2017 Mazda CX-9. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Brake fluid will damage painted surfaces. Be careful not to spill any on painted surfaces. In addition, if there is any brake fluid on the wiring harness, the wire insulation may corrode causing a malfunction such as a short circuit. If brake fluid gets on a painted surface or wiring harness, wash and flush it off completely with water immediately.

NOTE:

When in maintenance mode, the clearance between the disc pad and the disc plate expands.
When the maintenance mode is completed, perform the electric parking brake automatic adjustment.
With the electric parking brake automatic adjustment, the electric parking brake motor gear unit operation time is longer than normal.

Switch to the maintenance mode. (See MAINTENANCE MODE .)
Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
Remove the wheel and tire. (See WHEEL AND TIRE REMOVAL/INSTALLATION .)
Disconnect the electric parking brake motor gear unit connector.
