| Defect Summary: |
THE ANTI-LOCK BRAKE SYSTEM FAILS TO COMPLY TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS". MANUFACTURING TOLERANCES ON THE SWITCH CAN ALLOW THE WARNING BUZZER TO SOUND AT PRESSURES BELOW THE STANDARD 60 PSI. THE STEERING WHEEL BLOCKS THE DRIVER"S FIELD OF VIEW OF THE WARNING LIGHT. SOME OF THE TRUCKS REQUIRE .6 SECONDS, FOR THE AIR PRESSURE TO FALL FROM 95 PSI TO 5 PSI INSTEAD OF THE REQUIRED .55 SECONDS. ALSO, ON SOME OF THESE VEHICLES, THE BRAKES WOULD NOT RELEASE AFTER LOSS OF AIR IN THE REAR BRAKE RESERVOIR BY MEANS OF THE SERVICE BRAKE CONTROL. |
| Consequence Summary: |
|
| Corrective Summary: |
DEALER WILL INSTALL TWO LOW AIR PRESSURE SWITCHES TO ACTIVATE THE LOW AIR PRESSURE WARNING BUZZER AT A MINIMUM OF 60 PSI. AN AUDIBLE WARNING BUZZER WILL ALSO BE INSTALLED ON VEHICLES WHERE THE ANTI-LOCK WARNING LIGHT MIGHT BE OBSCURED BY THE STEERING WHEEL, AND VALVES AND FITTINGS WILL BE INSTALLED TO DECREASE THE TIME NECESSARY TO EXHAUST THE AIR FROM THE BRAKE CHAMBERS. |
