Product

Vehicles: ALEXANDER DENNIS WABCO TRISTOP SPRING BRAKE ACTUATOR. Units affected: 715

Reason

On some TRISTOP� actuators the chambers may not have been correctly assembled and the load from power spring and pressure is not fully taken. Under certain circumstances the parking side and the service sides of the actuator could separate and the actuator could lose functionality. Ultimately this could lead to a loss of braking functionality and/or brake failure. Critical applications are vehicles such as city buses or garbage collection vehicles (subject to a high parking brake frequency). Remedy: Identify and replace affected actuators.
