Recall 78V-234: 1974–1977 Dorsey Dorsey
DORSEY TRAILERS, INC. recall for service brakes, air, reported to NHTSA on Oct 20, 1978, covering about 220 vehicles.
The problem
The piston in the antilock valve could stick due to exposure to high concentrations of fluid contaminants that may collect in the trailer braking system. Consequently, no air would be delivered to the brake chambers normally supplied by that valve. This could result in a "no brake" condition on the affected axles. This constitutes a non-compliance to federal motor vehicle safety standard no. 121, "air brake systems".
The fix
The defective valve will be replaced without charge.
