1990 Cadillac Allante brake problems

SERVICE BRAKES

OVER THE LAST MONTH, WHILE BRAKING THE DRIVER INFO DISPLAY WOULD SHOW ANTILOCK-TRACTION DISABLED, THEN WOULD FLASH ANTILOCK OK, TRACTION OK. VEHICLE SEEMED TO BRAKE JUST FINE AND SINCE THE DISPLAY SAID IT WAS OK I DIDN'T THINK IT WAS A PROBLEM, THEN ON 9/20/2014 WHILE DRIVING HOME DOWN MY STREET THE CAR WOULD NOT STOP AND THE RED BRAKE LIGHT CAME ON THE DASH. THIS HAPPENED ALL WITHOUT WARNING. THE LAST TIME THE BRAKES WERE APPLIED IT SHOWED NO SIGNS OF TROUBLE. FROM WHAT I HEAR THIS IS A VERY COMMON PROBLEM FOR CADILLAC ALLANTE FROM 87-92. I KNOW THAT THERE WERE NOT MANY OF THESE CARS MADE (ABOUT 3000 PER YEAR) BUT IF THIS IS A COMMON PROBLEM THEN I FEEL THIS MUST BE ADDRESSED, SINCE IT IS SAFETY RELATED. MY GRANDSON IS GETTING HIS DRIVER'S LICENSE THE FIRST OF THE YEAR AND I WAS GOING TO GIVE HIM THIS VEHICLE...NOW I HAVE SECOND THOUGHTS..I CAN'T BELIEVE GM WOULD ALLOW SUCH A VEHICLE TO BE ON THE HIGHWAYS. THIS A VERY DANGEROUS SITUATION!!! THANK YOU FOR YOUR TIME

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

I RECIEVED AN ANTILOCK DISABLED MESSAGE AND WITHIN 1 MILE THE BRAKES TOTALLY FAILED. THE CAR STILL HAD GOOD BRAKE PEDAL, BUT NO BRAKES AT ALL. THE EMERGENCY BRAKES FAILED AS WELL. FORTUNATELY, IT WAS 3:30 AM AND NO TRAFFIC. I WAS ABLE TO SWING INTO AN EMPTY PARKING LOT AND CIRCLE UNTIL THE CAR CAME TO A STOP. UPON TALKING TO SEVERAL OTHER ALLANTE OWNERS, I FOUND OUT THAT THIS IS A FREQUENT OCCURANCE WITH THESE CARS. DOES SOMEONE HAVE TO BE KILLED BEFORE CADILLAC DOES SOMETHING ABOUT THIS POTIENTIALLY FATAL FLAW?

AFTER FAILURE AND NEAR ACCIDENT, CADILLAC CORPORATION SAID THEY HAD AN INEXPENSIVE WAY TO REMEDY PROBLEM. THEY INSTALLED A BOOSTER TO ADD PRESSURE TO THE PEDAL. COST WAS $700. THIS DID NOT WORK. ANOTHER FAILURE DRIVING HOME WHICH ALMOST CAUSED ANOTHER ACCIDENT. NOW TOLD MUST REPLACE THE PUMP WHICH I DID. COST $3,382. I ASKED FOR THE OLD PART. SAID THEY WOULD HAVE TO CHARE ME ANOTHER $500 CORE CHARGE. I UNDERSTAND THIS BOSH BRAKE SYSTEM WAS THE SAME BRAKE SYSTEM RECALLED ON CHRYSLER VEHICLES. ALTHOUGH MANY MORE CHRYSLERS WERE SOLD THEN CADILLAC ALLANTE'S THIS IS A SERIOUS PROBLEM THAT CAN CAUSE A MAJOR ACCIDENT AND LOSS OF LIFE. I AM TOLD THIS IS A MAJOR FAILURE IN ALLANTES'

ODI ACTION NUMBER: EA99-017 I GOT A MESSAGE ON MY MESSAGE CENTER THAT MY ALLANTE'S ABS SYSTEM WAS DISABLED SO I TOOK IT INTO MY DEALER. ON THE WAY THE BRAKES WENT TOTALLY OUT, ALMOST CAUSING AT LEAST ONE ACCIDENT. NOW I AM FINDING OUT FROM OTHER OWNERS OF CADILLAC ALLANTES THAT THIS IS HOW THE FOUND OUT ABOUT A MODEL WIDE PROBLEM. YOUR BRAKES GO OUT IS HOW YOU FIND YOU HAVE A PROBLEM WITH YOUR BRAKES. I HAD DRIVEN FEWER THAN TEN MILES AFTER RECEIVING THE WARNING. AND THE WARNING WAS NOT BRAKE FAILURE, BUT JUST ABS WHICH I HAVE NEVER REALLY USED. CADILLAC MADE VERY FEW OF THESE MODELS, BUT THE PROBLEM IS RAMPANT IN ALL OF THEM UP TO 1993. ARE YOU DOING ANYTHING ABOUT THIS?

I CANNOT APPLY BRAKES WITHOUT LOSING THE ANTILOCK SYSTEM. I RETAIN SOME BRAKING, BUT IT IS THE MANUAL BRAKING AND NOT THE ABS. THIS FAILURE STARTED AROUND 60000 MILES IN 1998 AND I'VE BEEN EXTREMELY CAUTIOUS IN DRIVING THIS VEHICLE KNOWING THAT I WON'T HAVE ABS. I'M A MEBER OF THE ALLANTE APPRECIATION GROUP AND HAVE READ APPROX (40) FAILURES OF SAME FROM OTHER ALLANTE OWNERS. PLEASE FEEL FREE TO CONTACT OUR WEBSITE AND YOU'LL ALWAYS FIND SOME MEMBER COMPLAINING OF A FAILURE OF THE ABS.

EVER SINCE I PURCHASED THIS VEHICLE EVERY TIME I STEP ON THE BRAKES I RECEIVE A MOMENTARY DROP IN THE BRAKE PEDAL, WHAT APPEARS TO BE A LOUD CLICKING COMING FROM UNDER THE DASH AREA AND THEN A REFIRMING OF THE BRAKE PEDAL JUST BEFORE COMING TO A STOP. ALL THE TIME THIS IS HAPPENING I AM RECEIVING A MESSAGE ON THE DRIVER INFORMATION CENTER, ANTI-LOCK DISABLED, TRACTION CONTROL DISABLED FOLLOWED BY ANTI-LOCK O.K., TRACTION CONTROL O.K. I DO NOT FEEL SAFE IN THIS VEHICLE AND SINCE I PURCHASED THIS VEHICLE I HAVE TALKED TO OTHERS WITH THE SAME OR SIMILAR PROBLEMS AND I DO NOT FEEL THIS IS AN ISOLATED INCIDENT. I FEEL THERE IS A DEFECT IN THE MANUFACTURING OF THE BRAKE SYSTEM COMPONENTS AND SHOULD BE REPAIRED BY THE MANUFACTURER REGARDLESS OF MILEAGE OR WARRANTY TIME.
