1976 FRUEHAUF FRUEHAUF Recalls (2)

Campaign:

78V227000 on 10/11/1979

Component:

Service brakes, air:disc:chamber

Manufactured:

07/31/1976 - 07/31/1977

Affected:

663

Defect:

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 this valve. this would result in a "no brake" condition on the affected axle(s). this failure would constitute a non-compliance to federal motor vehicle safety standard no. 121, "air brake systems".

Correction:

Vehicle will be inspected and, if necessary, antilock air valves will be replaced without charge.

Notes:

Vehicle description: freight and tank trailers.system: service brakes; antilock air valves.consequences of defect: loss of braking capability could result in a vehicleaccident.
