Brakes may require excessive time to release after brake application. A second defect is reduced holding power of the parking/emergency brakes due to entry of water in the rear brake chambers. Excessive release time does not comply with federal motor vehicle safety standard no. 121, "air brake systems".
Dealer will modify the vehicle by installing a quick release valve in the brake air system and by substitution of a stiffer brake pedal return spring. Rear brake chambers will be exchanged or modified, depending on the chamber make, to prevent water entry.
Vehicle description: heavy trucks; four wheel models. System: service brakes; parking brakes; air valve, pedal, brake chambers. Consequences of defect: failure of the service brakes to release reduces drivercontrol over vehicle and may result in an accident. Failure of theparking/emergency brakes may allow a parked vehicle to move without warning,possibly causing an accident and personal injury.
