1.
Remove some brake fluid from the reservoir.

4. Brake Caliper Piston - Enter the MAINTENANCE MODE

NOTE: If the HDS is not used, remove the electric parking brake actuator, and using a T45 TORX driver, turn the spindle clockwise until it comes to a lock.
2.
Select ADJUSTMENT from ABS/VSA menu with the HDS, then enter ENTER BRAKE PAD MAINTENANCE MODE from BRAKE PAD MAINTENANCE MODE, and follow the screen prompts. Make sure TRANSITION TO PAD EXCHANGE MODE HAS BEEN COMPLETED on the screen.

1. Brake Caliper Piston - Return (Without Using the HDS)
1.
Install the brake caliper piston compressor tool (A) on the caliper body (B).
2.
Press in the piston with the brake caliper piston compressor tool.
3.
Remove the brake caliper piston compressor tool.

2. Brake Pad - Install
1.

Wipe off the excess assembly paste from the retainers. Keep the assembly paste away from the brake disc and the brake pads.
4.
Install the brake pads (B) and pad shims (C) correctly with the indicator (D) on the bottom inside position.
NOTE:
If you are reusing the brake pads, always reinstall the brake pads in their original positions to prevent a temporary loss of braking efficiency.
Be careful not to damage or deform the pad return springs (E). If the pad return springs is damaged or deformed, replace the brake pad as an assembly.
The upper and lower pad return springs are different. During installation, make sure the pad return springs are in the proper positions.
5.

Brake pad thickness:
 
Standard:
10.0 mm (0.394 in)
 
Service limit:
1.6 mm (0.063 in)
2.
If any part of the brake pad thickness is less than the service limit, replace the brake pads as a set.
