The issue
THESE VEHICLES WERE BUILT WITH A FOOT CONTROLLED BRAKE VALVE THAT MAY, IF A COMBINATION OF CONDITIONS OCCUR, MALFUNCTION BY ALLOWING AIR PRESSURE TO BYPASS THE CONTROL PISTON "O" RING. IF PRESENT, THESE CONDITIONS MAY, WITHOUT WARNING, CAUSE OVERLY AGGRESSIVE VEHICLE BRAKING DURING NORMAL BRAKE APPLICATIONS RESULTING IN THE POTENTIAL FOR A VEHICLE CRASH. CORRECTION: ACTUATION PLUNGER UNDER BRAKE PEDAL WILL BE REPLACED AS WELL AS THE FLOOR MOUNTED BRAKE VALVE MOUNTING PLATE AND PEDAL MOUNTING BRACKET UNDER VALVE.
