BRAKE PAD REPLACEMENT
 
 
FRONT DISC BRAKE
Required Special Tool:
  • MB990520: Piston expander
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) Inner shim
(2) Outer shim
(3) Brake pad assembly
(4) Brake pad and wear indicator assembly
(5) 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 inner shim, outer shim, brake pad assembly, brake pad and wear indicator assembly and clip to the caliper support, and tighten the parts to the specified torque.
Specified torque: 50 ± 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.
