BRAKES

FRONT DISC BRAKE CALIPER ASSEMBLY
This caliper has a single 51.1 mm (2.012 in.) bore and is mounted to the brake caliper holder with two mounting
bolts. Hydraulic force, created by applying force to the brake pedal, is converted by the caliper to friction. The hy-
draulic 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.
REAR DRUM BRAKE ASSEMBLY
The drum brake assembly has a self shoe clearance adjusting system so that drum- to-shoe clearance is main-
tained appropriate at all times.
NOTE:
Replace all components included in repair kits used to service this drum brake. Lubricate parts as speci-
fied.
WARNING:
When servicing wheel brake parts, do not create dust by grinding or sanding brake linings or by
cleaning wheel brake parts with a dry brush or with compressed air. (A water dampened cloth should
be used.) Many wheel brake parts contain asbestos fibers which can become airborne if dust is
created during servicing. Breathing dust containing asbestos fibers may cause serious bodily harm.
If any hydraulic component is removed or brake line disconnected, bleed the brake system. The
torque values specified are for dry, unlubricated fasteners.
MASTER CYLINDER ASSEMBLY
The tandem master cylinder is similar in construction to an ordinary master cylinder, the principal differences being
that it has two pistons and that hydraulic pressure is developed in two chambers, one for front left & rear right brakes
and the other for front right & rear left brakes.
1. Master cylinder body
2. Master primary piston
3. Master secondary piston
4. Piston stopper bolt
5. Stopper bolt seal ring
6. Push rod
7. Piston stopper circlip
8. Master cylinder boot
“A” : Primary piston (For front left & rear right brakes)
“B” : Secondary piston (For front right & rear left brakes)
