NHTSA Campaign 97V030000

SERVICE BRAKES, AIR:DRUM:CHAMBER

Issued by THOMAS BUILT BUSES, INC. · Reported Mar 3, 1997 · 695 vehicles affected

What's wrong

CONTACT BETWEEN THE BRAKE CHAMBER AND THE SUSPENSION BEAM CAN RESULT IN DAMAGE TO THE BRAKE CHAMBER CLAMP BAND.

Consequence

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.

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.
