2001 Chevrolet Impala SERVICE BRAKES, HYDRAULIC

GETTING RUMBLING FEEL WHEN APPLYING BRAKES, ESPECIALLY BAD AT HIGHER SPEEDS. DEALER REPLACED ALL 4 ROTORS. MY CONCERN IS THE REPAIR ORDER STATED "WARPED ROTORS" WHEN IF FACT THE SERVICE MANAGER STATED THE ROTORS WERE PITTED, NOT WARPED. I WAS CONCERNED BEACUSE I WAS VERY CONSCIENTIOUS TO MAKE SURE EVERY TIME THE TIRES WERE ROTATED AND BALANCED THE WHEELS WERE TORQUED TO THE DESIGNED FT LBS. I HAVE CHECKED WITH SEVERAL OTHER DEALERS AND GARAGES THEY TELL ME THEY HAVE REPLACED MANY GM ROTORS FOR THE SAME PROBLEM OF PREMATURE FAILURE (PITTING). NORMALLY WITH WARPPED ROTORS YOU GET A VIBRATION AND SURGING AT LOW SPEEDS WHEN APPLYING BRAKES, I DID NOT HAVE THAT. I HAD RUMBLING AT 25 MPH AND HIGHER, ESPECIALLY BAD WHEN HARD BREAKING BETWEEN 55 & 65 MPH.*AK

APPROXIMATELY EVERY 10,000 MILES, CONSUMER HAS TO HAVE FRONT ROTORS AND FRONT PADS SERVICED AND REPLACED. *JG *NM

NO SUMMARY LISTED FOR ABOVE VEHICLE. *AK

BRAKES INOPERATIVE AT HIGHWAY SPEEDS IN THE RAIN BECAUSE THERE ARE NO BACKING PLATES. POTENTIAL FOR AN ACCIDENT WHEN IT RAINS. FINE AT LOW SPEED, BUT NO BRAKING OVER 50 MPH. ALSO NOTE-- PROVINCE OF "ONTARIO" & POSTAL CODE "L3M 1P8" IN CANADA. IT HAS BEEN A DRY SUMMER AND I SEE A POTENTIAL PROBLEM WHEN WINTER (AND SLUSH) ARRIVES. MR

ON 7-24-01 CALLED THE DEALER TO FIND OUT IF I HAVE ABS BRAKING SYSTEM ON MY CAR ,THEY TOLD ME I DID SO I TOLD THEM THAT THE ABS WARNING LIGHT DOESN'T COME ON WHEN YOU TURN THE IGN. ON LIKE THE OWNERS MANUAL SAIDS. THEY TOLD ME THAT AS LONG AS THE BRAKE LIGHT COMES ITS OK. SO I COMPLAINED TO THE CHEV. CUSTOMER SERVICE REPS. ABOUT THIS AND THE ANSWER I GOT WAS THE SYSTEM IS OKAY , AND THE REASON THE ABS LIGHT DOESN'T COME ON IS BECAUSE IN THE BEGINING OF THIS MODEL YEAR ABS WAS FREE,AND IN THE SECOND HALF IT COSTED 620.00 DOLLARS, WHAT ARE THEY SAYING???? IN THE OWNERS MANUAL IT STATES THAT EVER THE LIGHT COMES ON AND THE SYSTEM IS OKAY OR IT DOESN'T AND TO GET LOOKED AT SOON.*AK

WHEN SITTING ON A HILL AND TAKING FOOT OFF BRAKE VEHICLE WILL ROLL BACK VERY FAST, AND DRIVER HAS TO SLAM ON BRAKES, AND THEN GO FORWARD. CONSUMER FELT THIS WAS VERY DANGEROUS.*AK
