RECALL FOR SERVICE BRAKES, AIR : ANTILOCK
THE ANTI-LOCK BRAKE SYSTEM FAILS TO COMPLY TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS".

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.
