1983 GMC C7 Recalls — Canada & USA

The 1983 GMC C7 has two recalls, both involving the brake system, where failures can lead to a crash without warning. On the front axle, severe brake chatter can crack the welds on the brake chamber mounting brackets where the S-cam tube meets the chamber support. If a bracket fails, the front wheels lose braking power and steering control can be restricted. The second issue involves the dual compartment air reservoir, where a carbon steel check valve spring may have been installed in place of the correct material. That spring can corrode and fail over time, compromising the air pressure that the brake system depends on to function.
