I EXPERIENCE BRAKE PEDAL PULSATION (LOW SPEED ABS ACTIVATION) WHEN ROLLING TO A STOP. MY GMC ONSTAR REPORT SAYS THERE IS NOTHING WRONG WITH MY ABS BRAKING SYSTEM YET I HAVE THIS PROBLEM. THE PROBLEM SEEMS TO BE RUSTED AND/OR FROZE UP WHEEL SPEED SENSORS AS VERIFIED BY TWO DIFFERENT MECHANICS. I UNDERSTAND THEY WERE RECALLS BY GMC OF OTHER TRUCKS EXPERIENCING THIS SAME PROBLEM. I REALLY HATE TO PAY $750 FOR NEW FRONT WHEEL BEARING ASSEMBLIES. I WANT MY TRUCK RECALLED FOR THIS PROBLEM. THERE IS A GMC TECHNICAL BULLETIN 03-05-25-007D. I AM NOT SURE THE ABS WILL FUNCTION PROPERLY WHEN REALLY NEEDED?? *TR

MY VEHICLE HAS 76,800 MILES AND ALL OF THE BRAKE LINES ARE RUSTED AND NEED TO BE REPLACED. I UNDERSTAND THAT THERE MAY BE A RECALL FOR THIS PROBLEM. PLEASE FORWARD ANY INFORMATION RELATED TO THIS ISSUE. *KB

WHILE AT OUR TOWN DUMP ON THE 2ND OF NOVEMBER OF 2011, I PROCEEDED FROM 1 DROP OFF LOCATION TO THE NEXT (AS USUAL), WHEN AS I SLIGHTLY DEPRESSED MY BRAKE PEDAL TO SLOW, THE PEDAL WENT RIGHT TO THE FLOOR. I ALMOST RAN INTO ANOTHER VEHICLE HAD I NOT DEPRESSED MY EMERGENCY BRAKE. THERE WAS NOWHERE TO TURN TO AS VEHICLES WERE EVERYWHERE, "WOW"! NOT KNOWING WHAT WAS WRONG, I CONTINUED TO THE NEXT DROP OFF POINT WITH VIRTUALLY NO BRAKES. I USED THE E-BRAKE AGAIN TO STOP. I TOLD THE DUMP ATTENDANT WHAT JUST HAPPENED AND HE SAID, "THAT'S PROBABLY WHY YOU'RE SPEWING WHAT LOOKS LIKE BRAKE FLUID FROM YOUR LEFT REAR. SURE ENOUGH, UPON INSPECTION THE LINE BLEW. I GOT THE VEHICLE TO THE LOCAL GMC DEALER. LONG STORY SHORT, THEY WANTED $360 TO FIX THE BRAKE LINE. [XXX] THE SERVICE MANAGER SAID IT LOOKS LIKE THE REST OF THE LINES DON'T HAVE MUCH TIME LEFT EITHER. "NOT GOOD!" I GOT THE VEHICLE HOME, CALLED MY SON WHO IS A MECHANIC FOR A LOCAL JEEP DEALER AND HE FIXED THE LAST FOOT OR SO OF THE BRAKE LINE WHERE IT BLEW. HE SAID "DAD COME HERE". HE SHOWED ME UNDER THE HOOD WHERE THE VISIBLE BRAKE LINES ARE VIRTUALLY ROTTED AND PROBABLY READY TO GO. I AM PARTIALLY DISABLED AND OUT OF WORK. I COULDN'T AFFORD TO HAVE THE DEALER REPLACE THE WHOLE BRAKE LINE LET ALONE NOW HAVING TO REPLACE ALL THE LINES! I SAW ON THE INTERNET THAT THIS IS AN ONGOING PROBLEM. WHY IS THERE NO RECALL ON THIS? IF I WERE SOMEWHERE ELSE GOING EVEN FASTER, THIS COULD HAVE BEEN BAD. WHY ARE THE CAR COMPANIES NOT REQUIRED TO USE HIGHER QUALITY/MORE CORROSIVE RESISTANT LINES? YES I UNDERSTAND THAT WOULD RAISE THE STICKER PRICE, BUT FOR A LIFE? THIS IS BRAKES ON SOMETHING THAT ROLLS AT VERY HIGH SPEEDS WE'RE TALKING ABOUT HERE AND NOTHING IS BEING DONE ABOUT IT AS FAR AS I CAN SEE? PLUS MY TRUCK IS LESS THAN 7 YEARS OLD AS WELL AS ALL THESE OTHER VEHICLES AND I HAD ONLY 84,375 MILES ON IT WHEN IT HAPPENED. RECALL? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
