VEHICLE DESCRIPTION: MOTOR HOMES BUILT WITH MIDLAND-GRAU TK-2 ANTI-LOCK BRAKE SYSTEM (ABS). PRESSURE DIFFERENTIAL PROBLEMS BETWEEN FRONT AND REAR BRAKE SYSTEMS CAN RESULT IN BRAKING TIMING ISSUES WHICH CAN CREATE EXCESSIVE FRONT BRAKE WEAR.
Consequence & remedy
Consequence: THIS CONDITION CAN REDUCE FRONT BRAKE LIFE RESULTING IN INCREASED VEHICLE STOPPING DISTANCES.
Remedy: DEALERS WILL REPLACE THE QUICK RELEASE VALVE WITH A VALVE FROM ANOTHER VENDOR.
VEHICLE DESCRIPTION: CLASS A MOTOR HOME CHASSIS EQUIPPED WITH INDEPENDENT FRONT SUSPSION, WHICH UTILIZES A NORGREN VALVE AND NEWAY PILOT AIR CONTROL VALVES. THE PURPOSE OF THE NORGREN VALVE IS TO EXHAUST THE AIR SUSPENSION WHEN THE DRIVER ACTIVATES THE VEHICLE JACKS USED TO LEVEL THE VEHICLE FOR OVERNIGHT PARKING. THE NEWAY PILOT VALVE IS USED TO SPEED UP THE TIMING OF THE AIR EXHAUST. WHEN THE VEHICLE IS IN A DYNAMIC CONDITION, THE AIR SYSTEM PRESSURE CAN SEND SPIKES OF UP TO 230 PSI. THIS EXCEEDS THE PRESSURE RATING OF THE NEWAY PILOT VALVE CAUSING THE VALVE TO FAIL AND ALLOW THE AIR SYSTEM PRESSURE TO EXHAUST UNCONTROLLABILITY.
Consequence & remedy
Consequence: IF THERE IS AN AIR SUSPENSION FAILURE, IT COULD LEAD TO VEHICLE HANDLING PROBLEMS AND A LOSS OF VEHICLE CONTROL.
Remedy: DEALERS WILL MODIFY THE AIR PLUMBING TO REMOVE THE THREE (3) NEWAY PILOT VALVES (TWO FRONT SUSPENSION/ONE REAR SUSPENSION) FROM THE AIR SYSTEM. THE NORGREN VALVE WILL BE FULLY UTILIZED TO REPLACE THE VALVES IN THE FRONT SUSPENSION AND A MIDLAND VALVE WILL BE USED IN THE REAR SUSPENSION.
