PACCAR issued a recall on the T2000 model

Certain vehicles fail to comply with the requirements of CMVSS 106 - Brake Hoses. The air tube expander fitting, a components of the air brake system, is designed for a burst pressure of 800 psi instead of the required 1,200 psi. Expander failure would cause an air leak to occur when the foot brake or trailer hand brake is applied. Should this occur in conjunction with compressor failure, the resultant air loss would release pressure on the park brake springs. This could set the brakes on the rear axle, which could result in a loss of vehicle control and a crash causing property damage, personal injury or death. Correction: Dealers will inspect and, if necessary, replace the expander fitting with a compliant version.
