Parking Brake System Service
GENERAL INFORMATION
The braking system and ground speed control system
are both linked through the lock plate bracket (B, Figure
3) and pivot plate (O). These two parts disengage the
cruise mechanism and lock the parking brake. Locking
either mechanism triggers the parking brake / cruise
switch (B, Figure 1) and illuminates the indicator light in
the dashboard.
PARKING BRAKE LOCK MECHANISM
To lock the parking brake, first the brake pedal is
depressed, rotating the pivot plate (O, Figure 3) and
brake lever (P) past the locking plate bracket (B) (clock-
wise from top). Second the parking brake/cruise knob is
pulled up, rotating the locking plate (B) (clockwise from
top) so that the cruise release tabs (A, Figure 2) move
past each other. At this point, letting up on the brake
pedal allows the cruise release tabs to contact each
other back to back, locking the pivot plate (O, Figure 3)
and bracket lever (P) in the engaged position.
Depressing the brake pedal gives the cruise lock tabs (A,
Figure 2) enough clearance to rotate past each other,
and allows the parking brake knob to be depressed, dis-
engaging the parking brake.
