WHEN BRAKING ON WET PAVEMENT, BRAKE PEDAL GOES TO PEDAL STOP AND VEHICLE IS NOT STOPPING. THE DEALER HAS PUT ON BRAKE BOOSTER, ABS DUMP VALVE MASTER CYLINDER BLED AND ADJUSTED BRAKES. GMC WAS INVOLVED WITH DIAGNOSIS. THIS WAS DONE ONE YEAR AGO TRUCK STILL DOES THIS. I REALIZE RECALL UNDER WAY INVOLVING 4WD VEHICLES BUT NOT TWO WHEEL DRIVE. FROM WHAT I HAVE READ SOUNDS LIKE THE SAME PROBLEM. HOW SHOULD I GO ABOUT GETTING THIS RESOLVED? SO FAR ABOUT $1800.00 HAS BEEN PUT INTO THIS PROBLEM. I DO NOT KNOW WHERE TO GO GET A RESOLUTION TO THIS.

VEHICLE DESCRIPTION: CERTAIN 4-WHEEL DRIVE PICKUP TRUCKS AND SPORT UTILITY VEHICLES EQUIPPED WITH ABS (ANTILOCK BRAKING SYSTEM) MANUFACTURED FROM SEPTEMBER 1989 THROUGH AUGUST 1996. UNDER CERTAIN DRIVING CONDITIONS THE SWITCH WHICH SIGNALS THE ABS SYSTEM WHETHER THE VEHICLE IS IN 2-WHEEL OR 4-WHEEL DRIVE CAN MALFUNCTION CAUSING INCREASED STOPPING DISTANCES DURING ABS STOPS WHILE IN THE TWO-WHEEL DRIVE MODE.
Consequence & remedy
Consequence: IF THIS OCCURRED AT A TIME WHEN MINIMUM STOPPING DISTANCE WAS REQUIRED, A VEHICLE CRASH COULD OCCUR WITHOUT PRIOR WARNING.
Remedy: DEALERS WILL REPLACE OR REPAIR THE 4-WHEEL/2-WHEEL DRIVE SWITCH.
SIGNIFICANT WEAR CAN DEVELOP ON THE LOW AND REVERSE CLUTCH PREVENTING THE PARK PAWL FROM ENGAGING. THIS CAN PREVENT A "NO PARK" CONDITION TO OCCUR WHILE THE ENGINE IS RUNNING, CAUSING UNINTENTIONAL MOVEMENT OF THE VEHICLE WITHOUT OPERATOR ACTION. (THE "NO PARK" CONDITION WILL NOT OCCUR WHILE THE ENGINE IS OFF.)
Consequence & remedy
Consequence: UNINTENTIONAL VEHICLE MOVEMENT COULD RESULT IN A VEHICLE ACCIDENT AND INJURY TO PERSONS IN THE PATH OF THE VEHICLE.
Remedy: DEALERS WILL CHECK THE TRANSMISSION FLUID FOR CONTAMINATION WHICH WILL INDICATE IF THE LOW OR REVERSE CLUTCH IS WORN. IF THE TRANSMISSION FLUID SHOWS CONTAMINATION, THE TRANSMISSION WILL BE REPLACED.
