One problem related to brakes failed has been reported for the 1999 Chevrolet C1500. The most recently reported issues are listed below.
The truck has been to the dealer often and they admited they could not guarntee they have fixed the front end the service mgr crossed his fingers and with a response that he hope so we dont drive the truck often for fear of an accident either the wheels locking up or the brakes failing, he said they tighted a bolt on the subframe and that fixed the front end but a gm engr told me that truck does not have a subframe only vehicles with unibodies use subframes, I have documented all services and responses if needed.
