Figure 1  Mechanical Brake System

BRAKE SYSTEM OVERVIEW

General Description 

This vehicle is equipped with a mechanically activated 

rear drum brake system. The brake system consists of a 

brake and parking brake pedal, parking brake release 

linkage, compensator assembly, equalizer link, brake 

cables and self adjusting wheel brake assemblies (Figure 

1).
Mechanical brakes depend on the travel of the brake 

cables to move the brake shoes against the brake drums. 

The travel of the brake cables is controlled by the brake 

pedal. If the cables cannot travel far enough to absorb the 

slack (free travel) in the system and still apply the shoes 

to the drums, the braking effort at the wheel brake will not 

be adequate. The self adjusting mechanism in the wheel 

brakes requires enough cable travel at the wheel brake to 

work reliably. When the brake is released, there must be 

slack in the system so the brakes will release fully and the 

adjusters will function. Free pedal travel, pedal force, 

shoe to drum clearance and braking capability are closely 

related. It is very important to maintain the proper rela-

tionships to assure braking performance and the best 

wheel brake adjustment.

How the Brake Works

Pressing the brake pedal pulls the compensator assem-

bly and equalizer link, which are connected to the brake 

cables (Figure 1). The first part of the pedal travel 

removes slack from the system. Continued motion of the 

brake pedal pulls both the left and right brake cables. 

Each brake cable pulls a brake lever which pushes the 

rear brake shoe against the brake drum. When the rear 

shoe contacts the brake drum, it can no longer move rear-

ward. Additional pedal (and cable) travel causes the actu-

ator bracket (moving anchor) to move and applies force to
