VEHICLE DESCRIPTION: PASSENGER VEHICLES. SOME OF THESE VEHICLES HAVE INTERNAL FLUID LEAKS IN THE BRAKE HYDRAULIC CONTROL UNIT.
Safety Risk
WHEN THE REAR BRAKE PROPORTIONING, ANTILOCK BRAKE, TRACTION CONTROL, OR STABILITY CONTROL FEATURE IS ACTIVATED IN SOME DRIVING SITUATIONS, THE FEATURE MAY NOT PERFORM AS DESIGNED.
Remedy
DEALERS WILL INSPECT THE ABS HYDRAULIC MODULATOR UNIT AND IF NECESSARY, REPLACE THE HYDRAULIC MODULATOR.
VEHICLE DESCRIPTION: PASSENGER VEHICLES NOT EQUIPPED WITH THE ANTI-LOCK BRAKING SYSTEM (ABS). A PRESSURE CONSCIOUS REDUCING VALVE (PCRV) IN THE REAR BRAKES MAY BE SUBJECT TO CORROSION AND RESULT IN MALFUNCTION, WHEN OPERATED IN AREAS THAT USE SALT COMPOUNDS ON THE ROADWAY FOR DE-ICING OR DUST CONTROL.
Safety Risk
IF BOTH PCRV'S MALFUNCTION, VEHICLE HANDLING COULD BE ADVERSELY AFFECTED DURING BRAKING AS A RESULT OF THE REAR WHEELS LOCKING, INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL INSTALL IMPROVED PCRV'S IN THE REAR BRAKE SYSTEM. THIS RECALL WAS EXPANDED IN SEPTEMBER 2000 TO INCLUDE 1999 AND 2000 FORD CONTOUR, MERCURY MYSTIQUE AND COUGAR VEHICLES.
THE NUTS AND BOLTS THAT ATTACH THE REAR BRAKE ADAPTOR TO THE AXLE HOUSING FLANGE CAN LOOSEN AND EVENTUALLY SEPARATE. IF ONE OR MORE OF THE NUTS COME OFF THE BOLTS, DAMAGE TO THE PARKING BRAKE ASSEMBLY OR TO THE ANTILOCK BRAKE SYSTEM (ABS) SENSOR AND SENSOR RING (IF SO EQUIPPED) WILL OCCUR. IF ALL FOUR NUTS ON ONE END OF THE AXLE COME OFF THE BOLTS, DAMAGE TO THE BRAKE HYDRAULIC LINE OR THE PARKING BRAKE CABLE CAN OCCUR.
Safety Risk
OCCURRENCE OF ANY OF THESE CONDITIONS CAN RESULT IN A LOSS OF BRAKING CAPABILITY AND POSSIBLE ACCIDENT.
Remedy
DEALERS WILL INSPECT AND, IF NEEDED, INSTALL NEW BOLTS. IF ANY OF THE FASTENERS ARE DISCONNECTED, THE PARKING BRAKE AND ABS COMPONENTS WILL BE INSPECTED AND SERVICED.
