NOTE:
All brake fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and / or could result in major repair expense. They must be replaced with one of same part
number or with an equivalent part if replacement becomes necessary. Do not use a replacement part of
lesser quality or substitute design. Torque values must be used as specified during reassembly to assure
proper retention of all parts. There is to be no welding as it may result in extensive damage and weakening
of the metal.

GENERAL DESCRIPTION
DISC BRAKE CALIPER ASSEMBLY
This caliper is mounted to the brake caliper carrier with two caliper pin bolts. Hydraulic force, created by applying
force to the brake pedal, is converted by the caliper to friction. The hydraulic force acts equally against the piston
and the bottom of the caliper bore to move the piston outward and to move (slide) the caliper inward, resulting in
a clamping action on the disc. This clamping action forces the pads (linings against the disc, creating friction to
stop the vehicle.
NOTE:

Lubricate parts as specified. Do not use lubricated shop air on brake parts as damage to rubber compo-
nents may result. If any component is removed or line disconnected, bleed the brake system.
Replace pads in axle sets only. The torque values specified are for dry, unlubricated fasteners.

For identification of the brake caliper type, see maker name or mark on brake caliper as shown.

Before installing caliper (cylinder body) to carrier, check to ensure
that guide pin (pin bolt) inserted in each caliper carrier hole can be
moved smoothly in thrust direction.
NOTE:
Where temperature gets as low as ±30
C in cold weather, use
rubber grease whose viscosity varies very little even at ±40
C
(±40
F).
