Summary

REAR BRAKE RELAY VALVE CONTROL LINE WAS CONNECTED TO THE SECONDARY DOUBLE CHECK VALVE, RATHER THAN THE PRIMARY ONE. CONSEQUENCE OF DEFECT: THESE TRUCKS HAVE A TWO AXLE BRAKE SYSTEM EACH ON SEPARATE SYSTEMS TO AVOID TOTAL LOSS OF BRAKES. HOWEVER WITH THE MISCONNECTED LINES AND IF A RUPTURE OR LEAK OCCURS IN THE CONTROL LINE, THE FRONT AND REAR AXLE BRAKES WILL FAIL.

Remedy

PROPERLY CONNECT CONTROL LINE TO THE PRIMARY DOUBLE CHECK VALVE. RECHECK FOR PROPER OPERATION OF FRONT BRAKES.
