*1	Rear Disc Brake Piston
*2	Nut
*a	The nut moves inward in pad replacement mode

HINT:

When replacing the rear disc brake pad and rear disc, since the nut inside the rear disc brake cylinder assembly is in an advanced position, it is necessary to move the nut back inside the cylinder. The nut can be moved back using pad replacement mode.

Pad replacement mode

When Using the Techstream:

Select "EPB Full Release" using the Techstream.
NOTE:
The parking brake must be released.
Follow the Techstream display and select "Next".
NOTE:
- Make sure to perform this procedure with the power switch on (IG).
- Make sure that the brake pedal is not depressed when performing this procedure.
- When the system changes to pad replacement mode, DTC C060E-2A, C0613-2A or C13B8-00 may be stored. If the DTC is stored, clear the DTCs after the procedure (rear brake pad replacement, etc.) is complete.
HINT:

Once the operation finishes, the parking brake indicator light flashes slowly (1 second intervals) (nut moves back inside the cylinder and system enters pad replacement mode).

HINT:

After a short time passes, the parking brake actuator assembly operates, and once the assembly finishes operating, the parking brake indicator light flashes slowly (1 second intervals) (nut moves back inside the cylinder and system enters pad replacement mode).

Turn the power switch off.
