BRAKE PAD REPLACEMENT
 
 
Required Special Tool:
  • MB990520: Piston expander
  • MB991621: Piston driver
 
 
 
<FRONT>
 
 
cautionWhen replacing, replace both brake pads (right and left) as a set.
1. Remove the parts indicated in the figure, swivel the caliper body upward and retain it with a wire or similar tool.

2. Remove the following parts from the caliper support.
(1) Shim
(2) Brake pad assembly (brake pad and wear indicator assembly)
(3) Clip

3.
cautionKeep grease or other soiling off the pad and brake disc friction surfaces.
Clean the piston part, and press the piston into the cylinder using the special tool piston expander (MB990520).

4. Assemble the shim, brake pad assembly and clip to the caliper support, and tighten the lock pin to the specified torque.
Tightening torque: 44 ± 5 N·m (32 ± 4 ft-lb)
noteInstall the brake pad assembly (with wear indicator) to the inner side of the brake disc, making sure that the wear indicator is located on the top.

5. Assemble the shim, brake pad assembly and clip to the caliper support, and tighten the two bolts to the specified torque as shown.
Tightening torque: 35 ± 4 N·m (26 ± 2 ft-lb).
noteObserve the followings when you install the brake pad assembly:
  • Mount the brake pad with the wear indicator to the inside of the vehicle.
  • Projection behind the brake pad assembly should be seated in the groove of the piston.
