PARKING BRAKE ADJUSTMENT
NOTE: The integral parking/service brake mechanism has an
automatic adjusting feature and does not require periodic man-
ual adjustment. When parking brake components or rear brake
pads are replaced, the parking brake linkage must be initially
positioned to ensure proper parking brake system operation.
The only additional adjustment necessary is accomplished with
the parking brake hand lever.
