Figure 3 Parking Brake and Kick-Off Mechanism
Depressing the parking brake pedal moves the latch arm
against the catch bracket. As the parking brake is
depressed, the service brake is applied until the notch in
the latch arm engages with the catch bracket. The service
brake pedal is held in the applied (down) position by the
catch bracket. The latch arm is held in position by the ten-
sion in the brake linkage. The Parking Brake can be
released by two methods:
1. Depressing the service brake, which permits the
spring loaded Parking Brake pedal to return to its orig-
inal position, disengaging the latch arm from the catch
bracket. This is the preferred method which minimizes
wear on components.
2. Pressing the accelerator pedal rotates the kick-off
cam which forces the pedal latch arm to move away
from the catch bracket. The spring loaded Parking
Brake pedal returns to its original position, releasing
the brake.
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 4). The
brake compensator assembly applies a spring load to the
parking brake system and insures that the parking brake
remains under tension whenever it is engaged

Kick-Off Actuating Linkage
The kick-off actuating linkage may require periodic adjust-
ment to compensate for the normal wear. Replacement of
any linkage components will also require an adjustment.
