DT*: THE CONTACT STATED WHILE DRIVING 35 MPH ON NORMAL ROAD CONDITIONS, THE ABS LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO A CERTIFIED INDEPENDENT MECHANIC WHO DETERMINED THE ABS PUMP HAD NOT OUTPUT. THERE WAS A RECALL # 96V260000 PERTAINING TO THE ABS PROBLEM. THE MANUFACTURER DETERMINED THE RECALL WAS ALREADY PERFORMED ON THE VEHICLE. HOWEVER, THE CONTACT DID NOT BELIEVE THE MANUFACTURER STATEMENT WAS CORRECT. THE VEHICLE WAS PURCHASED IN 1995 AND THE LETTER WAS NEVER RECEIVED BY THE CONTACT. THE VEHICLE REMAINED AT THE MECHANIC SHOP BECAUSE THE VEHICLE WAS NOT SAFE TO OPERATE.
VEHICLE DESCRIPTION: VEHICLES EQUIPPED WITH ANTILOCK BRAKE SYSTEM (ABS). THE ANTILOCK BRAKE SYSTEM (ABS) HYDRAULIC CONTROL UNIT CAN EXPERIENCE EXCESSIVE BRAKE ACTUATOR PISTON SEAL WEAR WHICH COULD CAUSE PUMP-MOTOR DETERIORATION.
Consequence & remedy
Consequence: IF THIS OCCURS, THE ABS FUNCTION WOULD BE LOSE AND REDUCED POWER ASSIST WOULD BE EXPERIENCED DURING VEHICLE BRAKING. THE INSTRUMENT PANEL WARNING LIGHTS WILL SIGNAL SYSTEM IMPAIRMENT AND THE BASE MANUAL BRAKES WILL REMAIN FUNCTIONAL.
Remedy: DEALERS WILL TEST THE VEHICLE'S ABS AND REPAIR AS NECESSARY. THE WARRANTY ON ALL ABS COMPONENTS WILL BE EXTENDED TO 10 YEARS OR 100,000 MILES (EXCEPT FOR THE BRAKE ACTUATOR PISTON ASSEMBLY AND THE PUMP-MOTOR ASSEMBLY WHICH WILL HAVE A LIFETIME COVERAGE). OWNERS WILL BE REIMBURSED FOR PREVIOUS ABS COMPONENT REPAIR COSTS.
THERE MAY BE HYDRAULIC FLUID CONTAMINATION FROM CONDENSATION FORMATION THAT CAN PLUG THE ABS BRAKE BOOSTER PUMP FILTER; STRESS CORROSION OF THE MASTER CYLINDER SNAP RING HAS BEEN TRACED TO CHLORINE LEAKING FROM THE LOW PRESSURE HYDRAULIC HOSE WHICH MAY CAUSE IT TO BREAK; FRONT BRAKE HOSE TO TIRE INTERFERENCE WHICH MAY CAUSE FAILURE OF THE BRAKE HOSE.
Consequence & remedy
Consequence: CONTAMINATION OF THE HYDRAULIC FLUID CAN CAUSEMALFUNCTIONING OF THE ANTI-LOCK BRAKE SYSTEM; LOW PRESSURE HOSE LEAKAGE CAUSESLOSS OF BRAKE FLUID AND ALSO RESULTS IN CORROSION AND FAILURE OF THE MASTERCYLINDER SNAP RING, RESULTING COMPLETE BRAKE FAILURE; FAILURE OF THE FRONT BRAKEHOSE DUE TO HOSE TO TIRE INTERFERENCE WILL CAUSE FAILURE OF ONE HALF OF THEBRAKE SYSTEM RESULTING IN A LONGER STOPPING DISTANCE THAN EXPECTED.
Remedy: REPLACE ABS LOW PRESSURE HOSE; REBUILD MASTER BRAKE CYLINDER; INSPECT, SERVICE INTERFERENCE PROBLEMS, AND REPLACE FRONT BRAKE HOSE AS NECESSARY.
