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.

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

A REDUCTION OF BRAKING ABILITY AT A TIME WHEN MINIMUM STOPPING DISTANCE IS REQUIRED COULD RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING.
