PARKING BRAKE (Continued)
The parking brake mechanism is self-adjusting to
compensate for lining wear. As wear occurs, drive-to-
driven disc clearance increases. This causes the drive
disc ball bearings to move farther up the cam ramps
in the driven disc increasing the amount of rotation.
The extra rotation produced is enough to extend the
piston for adjustment.
STANDARD PROCEDURE
STANDARD PROCEDURE - AUTOMATIC
ADJUSTER LOCKING OUT
(1) Disconnect negative (-) cable from negative ter-
minal on battery. Be sure battery cable is isolated
from battery.
(2) Block tire and wheel assemblies so vehicle does
