12. Using Brake Shoe Gauge, Special Tool C-3919, or
equivalent, measure inside diameter of parking
brake drum portion of rotor. Set gauge.
13. Place Gauge (1) over parking brake shoes at wid-
est point.
14. Using adjuster star wheel (2), adjust parking
brake shoes until linings on both park brake
shoes just touch jaws on gauge. This will give a
good preliminary adjustment of parking brake
shoes, before a final adjustment is made at end of
this procedure.
15. Install hub and bearing with wheel speed sensor
as well as all components necessary to access it.
(Refer to 2 - SUSPENSION/REAR/HUB / BEAR-
ING - INSTALLATION)
16. Lower vehicle.
17. Perform final adjustment of parking brake shoes.
(Refer to 5 - BRAKES/PARKING BRAKE/SHOES
- ADJUSTMENT)
ADJUSTMENTS
PARKING BRAKE SHOE ADJUSTMENT
1. Place parking brake lever in “full released” position.
2. Raise and support vehicle. (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCEDURE)
3. Remove plug in parking brake shoe support to
access adjuster star-wheel (1).
NOTE: Through the access hole (2), rotate the
adjuster star wheel (1) in the following direction to
expand the shoes outward against the drum.
•
Left brake – Rotate star-wheel toward rear of
vehicle.
•
Right brake – Rotate star-wheel toward front of
vehicle.
4. Using an appropriate tool, turn adjuster star wheel
(1) until wheel will not rotate (dead lock).
5. Back off adjuster six detents (teeth).
6. Rotate wheel, checking for light drag. If drag is too
heavy, continue to back off adjuster one detent at a
time until light drag is present. Do not back off
star-wheel more than 17 detents from wheel lock.
