Brake Shoe: Adjustments

Fig. 5 Service brake adjustment:

The hydraulic drum brakes are self-adjusting and require a manual adjustment only after brake shoes have been relined or replaced. The adjustment is made as follows:
1. Determine inside diameter of brake drum using brake adjustment gauge, Fig. 5.
2. Reverse tool and adjust brake shoes to fit the gauge. Hold automatic adjusting lever out of engagement while rotating adjusting screw to avoid damaging screw slots.
