What NHTSA recorded
The involved vehicles do not conform to federal motor vehicle safety standard no. 121, "air brake systems". The required brake release time of 0.55 seconds may not be attainable due to disconnection of the rockwell skid control valve which had performed the relay valve and quick release functions.
Remedy
Dealer will inspect and, if necessary, install the components needed to bring the brake release time into compliance with the standard.
