The problem
CONTACT BETWEEN THE BRAKE CHAMBER AND THE SUSPENSION BEAM CAN RESULT IN DAMAGE TO THE BRAKE CHAMBER CLAMP BAND.
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.
What owners should do
DEALERS WILL INSPECT THE BRAKE CHAMBER FOR SIGN OF CONTACT. IF CONTACT IS INDICATED, THE BRAKE CAM SHAFT AND CHAMBER SUPPORT BRACKET WILL BE REPLACED, ELIMINATING THE POSSIBLITY OF CONTACT BETWEEN THE BRAKE CHAMBER AND THE SUSPENSION BEAM.
