7. Reduce the inside diameter measurement of the brake drum that was taken using Special Tool C-3919 (2)

by 1/64 of an inch. Reset Gauge, Brake Shoe, Special Tool C-3919 (2) or the equivalent used, so that the
outside measurement jaws are set to the reduced measurement. See Fig. 100.

8. Place Gauge, Brake Shoe, Special Tool C-3919 (2) , or equivalent over the park brake shoes. The special

tool must be located diagonally across at the top of one shoe and bottom of opposite shoe (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. Repeat step 8 above and measure shoes in both directions.

11. Install brake rotor on the axleshaft. See INSTALLATION.

12. 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.

13. Install disc brake caliper on caliper adapter. See INSTALLATION.

14. Install wheel and tire.

Adjustment can be made with a standard brake gauge or with adjusting tool. Adjustment is performed with the
complete brake assembly installed on the backing plate.

1. Be sure parking brake lever is fully released.

2. Raise vehicle so rear wheels can be rotated freely.

3. Remove plug from each access hole in brake support plates.

4. Insert adjusting tool through support plate access hole and engage tool in teeth of adjusting screw star

wheel. See Fig. 101.

CAUTION: Before moving vehicle, pump brake pedal several times to ensure the

vehicle has a firm enough pedal to stop the vehicle.

NOTE:

After parking brake lining replacement, it is recommended that the parking
brake system be conditioned prior to use. This is done by making one stop
from 25 mph on dry pavement or concrete using light to moderate force on
the parking brake hand lever.
