Wabco recalls

The Hand Brake Valve handle automatic locking function may not maintain the park position. The handle may remain in the lock only temporarily and flip back from the parking position into the driving position in which case the vehicle can runaway.

Fix: Recall the vehicles that are likely to be affected and exchange the Hand Brake Valve with a quality assured unit.

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). Long haul applications are not considered critical and thus do not require an exchange.

Fix: Identify and replace affected actuators.

In extreme cases overlapping of tolerances in conjunction with wear can potentially cause the bushing of the Foot Brake Valve (FBV) to move from its correct position. When this potential malfunction occurs it may not be possible to use the FBV to brake the vehicle.. However it is possible to use the handbrake instead to bring the vehicle to a controlled stop.

Fix: To recall the affected components and replace them with quality assured components.

It has been identified that in some cases overlapping of tolerances has the potential to make the black button of the PREV to stick in the pushed-in position when the trailer is coupled to the tractor unit. When this malfunction occurs the red warning lamp or signal for the trailer braking system on the dashboard of the truck will alert the driver that the reservoir air pressure in the trailer is dropping below 4.5 Bar. If this pressure falls below 2.5 Bar this will cause unintended braking of the vehicle.

Fix: To address the concern Wabco under the terms of the Code will contact customers who will be provided with a valve repair kit.

It has been identified that a disconnection of the air intake port may ocurr during service brake application. This can affect the correct functioning of the service brake and may cause the parking brake to apply inadvertently.

Fix: Recalled vehicles will have the brake assemblies replaced.
