VEHICLE DESCRIPTION: 1992-1994 CHEVROLET AND GMC SUBURBANS EQUIPPED WITH VACUUM POWER-BRAKE ASSIST AND EBC4 ANTI-LOCK BRAKE (ABS) MODULES. THESE VEHICLES EXHIBIT POOR BRAKE SYSTEM PERFORMANCE.

99V025000LightingFebruary 5, 1999 · 988,587 units

Defect

VEHICLE DESCRIPTION: PICKUP TRUCKS, CREW CABS, UTILITY TRUCKS AND SPORT UTILITY VEHICLES. THESE VEHICLES WERE BUILT WITH THE POLARITY OF THE WIRING FOR THE ZERO ADJUST BRAKE SWITCH REVERSED FROM WHAT WAS SPECIFIED ON THE SWITCH DRAWING. WITH THE REVERSED POLARITY, THE CONTACTS IN THE BRAKE SWITCH CAN WEAR OUT PREMATURELY. THE BRAKE SWITCH WILL PERFORM NORMALLY UNTIL THE BRAKE SWITCH CONTACTS WEAR OUT, RESULTING IN LOSS OF THE BRAKE LAMPS WITHOUT ANY WARNING TO THE DRIVER.

Consequence

THIS WOULD FAIL TO WARN A FOLLOWING DRIVER THAT THE VEHICLE IS BRAKING AND COULD LEAD TO A CRASH.

Remedy

DEALERS WILL REPLACE THE BRAKE SWITCH AND REVERSE THE WIRING.
