BRAKES

Read all of SAFETY and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.

the front shoe, pushing it against the brake drum. The

force applied to the front and rear shoes is approximately

equal. As the shoes contact the moving brake drum, the

shoes try to move in the direction of drum rotation. This

movement results in the typical brake shoe wear patterns.

Equalizer Link

The equalizer link balances braking between the driver

and passenger sides of the vehicle. Variations in wheel

brake adjustment, cable friction and manufacturing toler-

ances may cause the equalizer to be slightly misaligned.

This misalignment is normal.

Automatic Adjuster Mechanism

Never manually adjust the brakes at

the star wheel. Doing so will cause

permanent damage to the adjuster

assembly and result in a gradual loss of brakes.

The wheel brakes are equipped with an automatic

adjuster mechanism that is designed to compensate for

brake shoe wear and eliminate the need for manual brake

shoe adjustment. The brake adjuster is activated by

movement of the lever attached to the brake cable.

How the Parking Brake Works

The parking brake is operated by a smaller pedal which

extends across the top of the brake pedal. It is spring

loaded and attached to the brake pedal with a hinge pin

(Figure 2).
Pressing the parking brake pedal moves the latch arm

against the catch bracket attached to the chassis. As the

parking brake is pressed, the brake is applied until the

notch in the latch arm engages with the catch bracket.

The brake pedal is held in the applied (down) position by

the catch bracket.
The latch arm is held in position by tension in the brake

linkage. The parking brake can be released by two meth-

ods:
1.

Pressing the brake, which permits the spring loaded

parking brake pedal to return to its original position,

disengages the latch arm from the catch bracket.

This is the preferred method because it minimizes

wear on components.

Pressing the accelerator pedal rotates the kick-off

cam and forces the pedal latch arm to move away

from the catch bracket. The spring loaded parking

brake pedal returns to its original position, releasing

brake.

Figure 2 Parking Brake and Kick-Off Mechanism

Kick-Off Actuating Linkage

The kick-off actuating linkage may require adjustment to

compensate for the normal wear. Replacement of any

linkage components will also require an adjustment.

Compensator Assembly

The compensator assembly contains a spring, which is

compressed until the stop tube within the spring is

engaged and the linkage becomes solid (Figure 3). The

brake compensator assembly applies a spring load to the

parking brake system and ensures that the parking brake

remains under tension when it is engaged.
