1975 CHEVROLET H70 RECALL - #78V148000
RECALL FOR SERVICE BRAKES, AIR : ANTILOCK : CONTROL UNIT/MODULE
SOME ANTI-LOCK CONTROLLERS CONTAIN ELECTRONIC COMPONENTS WHICH WERE NOT MADE TO SPECIFICATIONS. IN THE EVENT THESE CONTROLLERS DEVELOP A FAILURE OF ANOTHER INTERNAL ELECTRIC COMPONENT, THE COMBINATION OF DEFECTS MAY CAUSE THE ANTI-LOCK VALVE SOLENOID (A COILED CURRENT CONDUCTING WIRE) TO BE CONTINUOUSLY ENERGIZED, PREVENTING APPLICATION OF THE BRAKES ON THE AXLE INVOLVED. HOWEVER, THE ANTI-LOCK BRAKING SYSTEM PERFORMANCE ON THE REMAINDER OF THE VEHICLE IS NOT AFFECTED AND THE DRIVER WARNING LIGHT IS NOT ACTUATED.
