HENDRICKSON MFG. CO. recall for service brakes, air, reported to NHTSA on Nov 15, 1979, covering about 1,246 vehicles.
The problem
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 fix
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.
