Recall 86V-086: 1983–1986 Chevrolet B6P042, 1983–1986 GMC B6P042
GENERAL MOTORS CORP. recall for service brakes, hydraulic, reported to NHTSA on Jul 7, 1986, covering about 4,299 vehicles.
The problem
Severe brake chatter may cause the brake chamber mounting brackets on either side to develop cracks in the weld area where the s-cam shaft tube attaches to the chamber support section. Consequence of defect: brackets can break, resulting in loss of braking ability at the front wheel, and possibly restrict steering, which could lead to a vehicle crash without prior warning.
The fix
As necessary, replace front brake chamber mounting brackets and install a front brake limiting valve.
Notes
System: brakes. Vehicle description: school buses equipped with a 7500 lb. Front axle and without a front brake limiting valve.
