Some of the involved vehicles do not comply with federal motor vehicle safety standard no. 121, "air brake systems". The air reservoir capacity IS below that allowed by the standard.
Risk and remedy
Remedy
Dealer will either replace the existing tank with a larger tank or add a second tank, without charge to owner.
The parking brake valves may have been incorrectly piped. If the parking brake piping IS incorrectly routed, there IS no way to set the tractor parking brakes independently of the trailer parking brakes. This could cause the parking brakes to back off while the trailer air supply IS being charged, causing the tractor to roll.
Risk and remedy
Remedy
Trailer air supply will be moved from the discharge side of the tractor parking valve to the discharge side of the combination parking valve. This service will be done at no charge.
