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.
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.

10. Repeat step 8 above and measure shoes in both directions.
11. Install brake rotor on the axle shaft.
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.
14. Install wheel and tire.
