CAUTION:
Do not twist or stretch the brake hose.
3. Remove pads, pad retainers and multilayered shims from torque
member.
CAUTION:
When removing the pad retainer from the torque member,
lift it in the direction indicated by the arrow as shown so
that it does not deform.
INSTALLATION
1. Apply Molykote M-77 grease or equivalent to between multilayered shims and brake pads. Install inner
multilayered shim to inner pad, and outer multilayered shim to outer pad.
2. Apply Molykote 7439 grease (A) to the pad retainer as shown.
3. Attach pad retainers to torque member, then install brake pads
and multilayered shim assemblies.
CAUTION:
When attaching pad retainer, attach it firmly so that it is
flush with torque member as shown.
4. Press in piston until pads can be installed, and then install caliper to torque member.
CAUTION:
In the case of replacing a pad with new one, check a brake fluid level in the reservoir tank because
brake fluid returns to master cylinder reservoir tank when pressing piston in.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press piston.
