1976 Mack RS recalls 4
Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do
- The problem
- An axle "no brake" condition could result from an eaton controller internal electrical malfunction. This condition may cause the anti-wheel lock valve solenoid to be continuously energized and prevent the brakes from being applied on one of the axles. As a result, the anti-wheel lock warning lamp is not activated.
- The fix
- The dealer will inspect and, if necessary, replace the anti-wheel lock controller without charge to owner.
- The problem
- A design deficiency exists in the air dryer piping in the area of the pressure relief valve and compressor governor control link. Moisture is passed and builds up in this relief valve and control line. In freezing ambient temperatures, this moisture may freeze, allowing the chassis air system pressure to exceed 150 psi. Excessive air system pressure can cause separation of air piping connections and air system valve failure.
- The fix
- The dealer will relocate the air system compressor governor line and pressure relief valve to eliminate moisture accumulation.
- The problem
- The front wheel aluminum hubs on the involved vehicles may be subject to cracks which may progress circumferentially around the barrel of the hub. This could lead to a fracture in the "barrel" position of the hub and complete hub failure.
- The fix
- Dealer will install steel hubs in place of aluminum hubs without charge to owner.
