## What is wrong

THE DUAL AIR RESERVOIRS OF SOME TRUCKS WERE EQUIPPED WITH CARBON STEEL SPRINGS INSTEAD OF STAINLESS STEEL SPRINGS, AS INTENDED. THE CARBON STEEL SPRING IS MORE SUSCEPTIBLE TO RUSTING THAN THE STAINLESS STEEL SPRING. THIS RUSTING COULD CAUSE THE CHECK VALVE TO FAIL, CAUSING TOTAL LOSS OF FRONT AND REAR BRAKES.


## The remedy

THE AIR TANK WILL BE INSPECTED AND, IF NECESSARY, THE AIR VALVE WILL BE REPLACED WITH ONE CONTAINING A STAINLESS STEEL SPRING.


## Notes

VEHICLE DESCRIPTION: MEDIUM TRUCKS EQUIPPED WITH AIR BRAKES.SYSTEM: SERVICE BRAKES; AIR SUPPLY CHECK VALVE.CONSEQUENCES OF DEFECT: IF AN AIR LEAK WERE TO OCCUR AND THE DRIVER DID NOTHEED WARNINGS, AN ACCIDENT COULD RESULT.
