Read all of Section B and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
Fig. 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 ser-
vice brake pedal is held in the applied (down) position by
the catch bracket. The latch arm is held in position by
the tension 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 (Ref. Fig. 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
adjustment to compensate for the normal wear.
Replacement of any linkage components will also
require an adjustment.
