Reported Nov 15, 19791,246 vehicles affectedHENDRICKSON MFG. CO.Built Apr 1, 1973 – Oct 1, 1978

The defect

The low air pressure switches used on some of the involved vehicles have a manufacturing tolerance that issues a warning only when the pressure drops a few pounds per square inch below 60 psi. As a result, they do not comply with federal motor vehicle safety standard no. 121, "air brake systems".

The remedy

If the owner, upon receipt of a post card, indicates a compliance, the dealer will reimburse owner $5.00 for cost of test. If owner indicates a non-compliance, the dealer will send two replacement switches and a check for $5.00 to cover both the system test and switch replacement.
