Defect
On brakes for heavy-duty buses, improper heat treatment of the expander wedges results in insufficient hardness. Repeated brake applications cause the wedges to wear and braking force to change. In the worst case, the wedges may be damaged and wheel braking may be lost.
Corrective action
On all vehicles, inspect the serial number of the affected expander and replace any identified unit with a good part.
