The defect
CONTACT BETWEEN THE BRAKE CHAMBER AND THE SUSPENSION BEAM CAN RESULT IN DAMAGE TO THE BRAKE CHAMBER CLAMP BAND.
The risk
IF THE DAMAGE TO THE CLAMP BAND RESULTED IN BAND BREAKAGE, THE CHAMBER COULD COME APART RESULTING IN LOSS OF THE SERVICE BRAKES. THE EMERGENCY BRAKES WOULD AUTOMATICALLY APPLY.
The remedy
DEALERS WILL INSPECT THE BRAKE CHAMBER FOR SIGNS OF CONTACT. IF CONTACT IS INDICATED, THE BRAKE CAM SHAFT AND CHAMBER SUPPORT BRACKET WILL BE REPLACED, ELIMINATING THE POSSIBILITY OF CONTACT BETWEEN THE BRAKE CHAMBER AND THE SUSPENSION BEAM.
