I OWN A 2001 CHEVY SILVERADO EXTENDED CAB 4X4, THERE WAS A RECALL AROUND 2005 FOR THE ABS ENGAGING AT SLOW SPEEDS. THE SERVICE WAS COMPLETED IN 2006. ABOUT 6 MONTHS AGO, THE ABS STARTED DOING IT AGAIN. THE DEALER SAID THEY ALREADY DID THE RECALL SERVICE SO I NEED TO PAY FOR THE REPAIRS THIS TIME. I BELIEVE THAT IF THE ORIGINAL RECALL SERVICE DIDN'T FIX THE PROBLEM, THAT IT SHOULD BE FIXED AGAIN. TRUCK HAS AROUND 104,000 MILES ON IT. THE ABS STARTED WORKING IMPROPERLY AT ABOUT 100,000 MILES. I HAVE HAD NO CRASHES YET BECAUSE OF THIS. *TR

2001 CHEVROLET 1500 EXT. CAB 4WD TRUCK ABS SYSTEM ACTIVATES AT LOW SPEED. THE INCIDENT OCCURED IN A PARKING LOT AS THE TRUCK WAS PULLING INTO A PARKING SPACE. THE ABS SYSTEM ACTIVIATED AND THERE WAS A COMPLETE LOSS OF BREAKING POWER. THE TRUCK HIT THE CAR IN THE PARKING SPACE OPPOSITE THE TRUCK. UPON INSPECTION OF THE TRUCK, THE FRONT ROTORS WERE ALMOST COMPLETELY ABSENT OF A USABLE WEAR SURFACE ON THE INSIDE OF THE ROTOR, THE EXTERNAL SIDE OF THE ROTOR DID NOT EXHIBIT THE SAME PROBELM. NEW ROTORS WERE INSTALLED WITH NEW PADS AT OWNER'S EXPENSE. ABS ACTIVATION AT LOW SPEED THEN STILL OCCURRED. I PURCHASED A SUBSCRIPTION FOR THE ALLDATA WEBSITE TO RETREIVE APPLICABLE SERVICE BULLETINS. THE SERVICE BULLETIN LISTS THE WHEEL SPEED SENSOR AS THE POSSIBLE FAULT. UPON EXAMINATION, THE SENSOR ALSO HAD THE SAME RUST PROBLEM AS THE ROTOR. THE SENSERS WILL ALSO BE REPLACED A OWNER'S EXPENSE ($110/PER SENSOR). THE WAS NO MENTION OF ANY ROTOR PROBLEMS IN THE BULLETIN. A 2001 VEHICLE WITH 85,000 MILES SHOULD NOT HAVE THE ROTOR DAMAGE THAT EXISTED. I HAVE SAVED THE ROTORS AS AN EXAMPLE. ALSO, THE ABS ACTIVATION'S COMPLETE LACK OF BREAKING POWER, BEYOND WHAT IS EXPECTED IN NORMAL ABS ACTIVATION CIRCUMSTANCES, MAKE ME LUCKLY TO HAVE HIT ANOTHER VEHICLE AND NOT A PERSON.

I OWN A 2001 SILVERADO 4X4 AND THERE IS NOTHING BUT PROBLEMS FROM THE BRAKES. I HAD TO REPLACE THE REAR BRAKES AT 30000 MILES BECAUSE OF A POOR STEEL WHICH CAUSED THE ROTORS TO FLAKE AND PIT APART WHICH IN TURN CAUSED FAILURE OF THE REAR BRAKES. MY SERVICE MANAGER AT THE GM DEALER TOLD ME TO REPLACE THE ROTORS WITH AFTER MARKET BECAUSE THEY ARE OF BETTER QUALITY AND CHEAPER. AFTER OVER $400 FOR THE PARTS PLUS LABOR, THE BRAKES ARE NOW FUNCTIONING. THEN 4 MONTHS LATER I COME TO FIND OUT THAT MY ABS TEND TO COME ON WHEN I SLOW TO A STOP, THEY ACTIVATE AT APPROXIMATELY 5MPH AND BELOW. THEY DO THIS ON ANY SURFACE AT ANY GIVEN TIME. THIS HAS CAUSED ME TO BRAKE FURTHER INTO INTERSECTIONS AND CROSSWALKS AS THE ABS GRAB AND RELEASE. I TAKE IT TO THE DEALER AND THEY TELL ME THAT THERE IS A SERVICE BULLETIN OUT TO FIX THIS. I WILL NEED TO SPEND MORE $ AND HOPE TO HAVE DECENT BRAKES. I AM GETTING VERY FED UP WITH THE PROBLEMS ON THIS VEHICLE. *AK
