Brake Shoe: Adjustments

Drum Brake Assembly:

Although the brakes are self-adjusting, an initial adjustment will be necessary after a brake repair. The initial adjustment can be obtained as follows:

1. Determine inside diameter of drum brake surface using brake shoe gauge D81L-1103-A or equivalent. Adjust brake shoe diameter to fit gauge. Hold automatic adjusting lever out of engagement while rotating adjusting screw and ensure that screw turns freely.
2. Install drum and wheel assembly, then adjust wheel bearings.
3. Complete adjustment by applying brakes several times, then check brake operation by making several stops from varying speeds.
