THIS BULLETIN APPLIES TO 2500 SERIES 4X4 VEHICLES THAT ARE CONTINUOUSLY OPERATED A 75% OR GREATER GVW AND HAVE THEIR REAR SUSPENSION ALTERED TO INCREASE RIDE HEIGHT AND ARE BUILT AFTER THE FOLLOWING DATES:
Those vehicles are equipped with a rear height sensing valve that adjusts brake pressure to the rear brakes based upon the distance between the vehicles frame and rear axle.
In situations where the vehicle is operated ALL THE TIME at or above 75% of the GVW AND the vehicle suspension has been altered, removal of the rear height sensing device may be necessary to help prolong the front pad life and provide suitable braking performance.
CAUTION: THIS PROCEDURE SHOULD ONLY BE PERFORMED ON 2500 SERIES 4X4 VEHICLES THAT ARE CONTINUOUSLY OPERATED AT 75% OR GREATER GVW AND HAVE HAD THEIR REAR SUSPENSION ALTERED.
