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.
