3. Remove upper and lower sliding pin bolts. Refer to
"BRAKE CALIPER ASSEMBLY : Exploded View"
.
NOTE:
Note the pin orientation during removal. The lower sliding pin
contains a bushing.
4. Remove the brake caliper from the torque member. Leaving the brake hose attached, reposition the brake
caliper aside with wire.
CAUTION:
Do not twist or stretch brake hose.
5. Remove the brake pads, shims, and shim covers from the torque member.
6. Remove the brake pad retainers from the torque member.
CAUTION:
When removing the brake pad retainers from the torque
member, lift it in the direction indicated by the arrow as
shown so that it does not deform.
INSTALLATION
Installation is in the reverse order of removal.
• Apply Molykote AS-880N grease or equivalent between the outer brake pad, outer shim cover and outer
shim and between the inner shim and inner brake pad. Install outer shim and outer shim cover to outer brake
pad. Install inner shim and inner shim cover to inner brake pad.
CAUTION:
• The inner shim cover (LH) (1) is different than the inner shim
cover (RH) (2). Install the inner shim covers in the correct
position.
• Replace brake pad shims and covers as a set if any corro-
sion or damage exists.
• Apply Molykote 7439 grease or equivalent between brake pad
retainers and brake pad ends. Install brake pad retainers and
brake pads to torque member.
CAUTION:
• Make sure the brake pad retainers are fastened properly to
the torque member.
• Replace brake pad retainers if damage exists.
• Press the piston into the cylinder bore of the caliper using a suitable tool.
• Check brake fluid level and refill as necessary. Refer to
• Burnish contact surface between brake pads and disc brake rotors. Refer to
.
