1997 CHEVROLET TAHOE — SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

I HAVE BEEN INVOLVED / RESPONSIBLE FOR 2 REAR END COLLISIONS THAT HAVE OCCURRED AS A RESULT OF MY ABS SYSTEM NOT STOPPING MY VEHICLE. THE FIRST TIME THIS HAPPENED I FELT THAT THE BRAKES DID NOT OPERATE CORRECTLY, BUT CONTINUED TO OPERATE THE VEHICLE. JUST LAST WEEK I WAS INVOLVED IN AN ACCIDENT AT LOW SPEED WITH MORE THAN SUFFICIENT STOPPING DISTANCE AND THE VEHICLE SLID INTO THE REAR OF OTHER. I HAVE NOT HAD ANY ACCIDENTS IN OVER 20 YEARS WITH MULTIPLE VEHICLES AND TO HAVE TWO SIMILIAR ACCIDENTS WITHIN A YEAR OF EACH OTHER FOR THE SAME CAUSE LEADS ME TO SUSPECT SOMETHING IS WRONG. HAVE THERE BEEN OTHER COMPLIANTS REGARDING THE ABS CAPABILITY IN CHEVY TRUCKS? *AK
