POWER–ASSISTED BRAKE SYSTEM
Disc Brake
Front Disc Brake
Rear Disc Brake (4 4 Model)
The disc brake assembly consists of a caliper, piston,
rotor, pad assembly and support bracket. The caliper
assembly has a single bore and is mounted to the support
bracket with two mounting bolts. The support bracket
allows the caliper to move laterally against the rotor. The
caliper is a one–piece casting with the inboard side
containing the piston bore. A square cut rubber seal is
located in a groove in the piston bore which provides the
hydraulic seal between the piston and the cylinder wall.
NOTE:
1. Replace all components included in repair kits used to
service this caliper.
2. Lubricate rubber parts with clean brake fluid to ease
assembly.
3. If any hydraulic component
disconnected, it may be necessary to bleed all or part
of the brake system.
4. Replace pads in axle sets only.
5. The torque values specified are for dry, unlubricated
6. Perform the service operation on a clean bench free
Operation
Hydraulic pressure, created by applying the brake pedal,
is converted by the caliper to a stopping force. This 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 rotor. This clamping action forces the linings against
the rotor, creating friction to stop the vehicle.
