1800 SRM 1037 Description and Operation
General
The main components of the parking brake system
are:
• Parking brake switch
• Solenoid valve
• Parking brake caliper This parking brake is for use on hydraulic brake sys-
tems only.
Description and Operation
The parking brake system uses a disc brake that
is installed at the rear of the differential housing.
See Figure 1 for typical system configuration. The
spring-applied caliper is installed on the differential
housing. The brake rotor is installed on the pinion
shaft.
When hydraulic pressure is released, the springs in-
side the brake expand to force the piston and lin-
ings against the disc. To release the brake, hydraulic
pressure must be applied to release the springs. The
brake can be released manually if hydraulic pressure
is not available.
The operation of the parking brake is controlled by
a solenoid valve for the parking brake. The sole-
noid is operated by a switch on the instrument panel.
The solenoid is normally energized during operation
for oil pressure to compress the spring to release the
parking brake.
