The problem
UNDER CERTAIN CONDITIONS, CONTACTS IN BRAKE SYSTEM RELAY COULD REMAIN CLOSED, CAUSING THE BRAKE PUMP MOTOR TO RUN CONTINUOUSLY, CAUSING IT TO OVERHEAT AND EVENTUALLY FAIL. CONSEQUENCE OF DEFECT: SHOULD THE BRAKE SUPPLY MOTOR FAIL, THE POWER ASSIST TO THE FRONT BRAKES WILL BE LOST, AND AFTER ABOUT 10 TO 15 NORMAL BRAKE STOPS, LOSS OF REAR BRAKE FUNCTION WILL RESULT, CAUSING INCREASED STOPPING DISTANCE. HOWEVER, THE INSTRUMENT BRAKE WARNING LIGHT WILL ILLUMINATE PRIOR TO REDUCED BRAKING CAPABILITY AND IF WARNING IS NOT HEEDED, AN ACCIDENT MAY OCCUR.
What owners should do
REPLACE PUMP MOTOR RELAYS.
