BRAKES-MAINTENANCE & ADJUSTMENT
NOTICE Refer to AnƟ-Lock Brake System Maintenance Manual for operaƟonal check and service instrucƟons.
The wheel brakes are equipped with slack adjusters for easy brake adjustment to compensate for brake lin- ing wear. It is recommended that slack adjuster arm travel be held to a minimum for most efficient braking acƟon. The brakes should be adjusted when total arm travel reaches 1-1/2”. To adjust brakes, depress lock sleeve on slack adjuster, then turn adjustment screw as required. Make sure lock sleeve returns to lock posiƟon when adjustment is complete. Every 5000 miles, the brake camshaŌs should be lubricated with approved chassis lubricant. Every 10,000 to 25,000 miles, the brakes should be serviced as follows: 1. Remove wheels and hubs. 2. Inspect brake roller shaŌs, cam rollers, anchor pins, camshaŌ sup-port bushings, spider bushings and camshaŌ for wear and replace if necessary. Lubricate these parts with chassis lubricant upon re- assembly. 3. Inspect brake linings for wear, loose rivets and any signs of grease on the braking surface. Oil-soaked linings are not reusable and must be replaced. Check to ensure that the linings have not worn to the point that rivet heads are contacƟng inside surface of drum. Reline or replace brake shoes if neces- sary. 4. Check inside surface of drum. RebooƟng of drums is not recommended, as the strength of refaced drums is greatly reduced. If drum is worn, replace it. 5. Service the wheel bearings and seals if required. Reassemble hubs and wheels.
