Parking Brake Shoe: Adjustments
PARK BRAKE SHOES (WITH REAR DISC BRAKES)CAUTION: Before adjusting the park brake shoes be sure that the park brake pedal is in the fully released position. If park brake pedal is not in the fully released position, the park brake shoes can not be accurately adjusted.
1. Raise vehicle.
2. Remove tire and wheel.
Disc Brake Caliper:

3. Remove disc brake caliper from caliper adapter.
4. Remove rotor from hub/bearing.
NOTE: When measuring the brake drum diameter, the diameter should be measured in the center of the area in which the park brake shoes contact the surface of the brake drum.
Measuring Park Brake Drum Diameter:

5. Using Gauge, Brake Shoe, Special Tool C-3919 or an equivalent, accurately measure the inside diameter of the park brake drum portion of the rotor.
Reading Park Brake Drum Diameter:

6. Using a ruler that reads in 64th of an inch, accurately read the measurement of the inside diameter of the park brake drum from the special tool.
Setting Gauge To Park Brake Shoe Measurement:

7. Reduce the inside diameter measurement of the brake drum that was taken using Special Tool C-3919 by 1/64 of an inch. Reset Gauge, Brake Shoe, Special Tool C-3919 or the equivalent used, so that the outside measurement jaws are set to the reduced measurement.
Adjusting Park Brake Shoes:

8. Place Gauge, Brake Shoe, Special Tool C-3919 or equivalent over the park brake shoes. The special tool must be located straight across at the center (widest point) of the park brake shoes.
9. Using the star wheel adjuster, adjust the park brake shoes until the lining on the park brake shoes just touches the jaws on the special tool.
10. Install rotor on hub/bearing.
11. Rotate rotor to verify that the park brake shoes are not dragging on the brake drum. If park brake shoes are dragging, remove rotor and back off star wheel adjuster one notch and recheck for brake shoe drag against drum. Continue with the previous step until brake shoes are not dragging on brake drum.
12. Install disc brake caliper on caliper adapter.
13. Install wheel and tire.
14. Tighten the wheel mounting nuts in the proper sequence until all nuts are torqued to half the specified torque. Then repeat the tightening sequence to the full specified torque of 129 Nm (95 ft. lbs.).
15. Lower vehicle.
16. Apply and release the park brake pedal one time. This will seat and correctly adjust the park brake cables.
CAUTION: Before moving vehicle, pump brake pedal several times to ensure the vehicle has a firm enough pedal to stop the vehicle.
17. Road test the vehicle to ensure proper function of the vehicle's brake system.
