2001 Toyota Prius SERVICE BRAKES, HYDRAULIC

WHEN I AM BRAKING AND GO OVER A BUMP OR DIP IN THE ROAD THE BRAKES STOP WORKING AND I IMMEDIATELY HAVE TO LET UP ON THE BRAKE AND REAPPLY. THIS HAS HAPPENED SEVERAL TIMES BUT DID NOT THINK ANYTHING OF IT UNTIL THE LATEST RECALLS FOR TOYOTA. THIS IS HAPPENING WITH MY 2001 PRIUS. YES I SAID 2001. THIS HAS HAPPENED MANY TIMES IN THE PAST 9 YEARS. I THOUGHT IT WAS NORMAL UNTIL THE RECENT REPORTS OF NEWER VEHICLES HAVING THIS ISSUE. MY VEHICLE IS 9 YEARS OLD. *TR

TL*THE CONTACT OWNS A 2001 TOYOTA PRIUS. THE CONTACT DETECTED TOXIC LEVELS OF MERCURY INSIDE OF THE VEHICLE. THE CONTACT STATED THE MERCURY PROBLEM WAS CONTRIBUTED TO A SPECIFIC TYPE OF METAL CONTENT IN THE BRAKE PADS. THE CONTACT WAS ADVISED BY A PHYSICIAN THAT A CHRONIC EXPOSURE OF MERCURY WAS IN HIS BODY WHICH RESULTED TO SUCH SYMPTOMS AS FATIGUE, ITCHY SKIN, HAIR LOSS AND A TINGLY SENSATION WITHIN THE BODY. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THEY DID NOT HAVE THE EQUIPMENT TO PERFORM A DIAGNOSIS FOR LEVELS OF MERCURY. THE CONTACT PLANNED TO REPLACE THE BRAKE PADS DUE TO THE SAFETY RISK INVOLVED. THE FAILURE MILEAGE WAS APPROXIMATELY 175,000.

I HAVE A 2001 PRIUS THAT ALSO HAS A PROBLEM WITH BRAKING, SIMILAR TO THAT DESCRIBED WITH THE 2010 MODEL. AT LOW SPEEDS WHEN THE CAR HITS A BUMP OR POTHOLE THE BRAKING IS MOMENTARILY LOST, BUT THEN RESUMES WITHIN 1-2 SECONDS. IN ~ 2003 I HAD A VERY LOW SPEED COLLISION FROM THIS (ABOUT $1000 DAMAGE TO THE HOOD SHEET METAL), BUT HAVE NOW LEARNED TO COMPENSATE FOR IT (BASICALLY APPLY BRAKES HARD AND WAIT FOR BRAKING TO RESUME AFTER THE PAUSE). I HAD REPORTED THIS TO THE DEALER ON SEVERAL EVALUATIONS, INCLUDING AFTER THE ACCIDENT, AND WAS TOLD THAT NO PROBLEM COULD BE IDENTIFIED. I AM REPORTING THIS BECAUSE IT IS REMARKABLY SIMILAR TO WHAT IT PURPORTED TO BE A NEW PROBLEM WITH THE 2010 PRIUS. IT IS NOT NEW. PLEASE FEEL FREE TO CONTACT ME IF YOU WOULD FIND OTHER INFORMATION USEFUL. *TR

ON 12/21/06 THE BRAKE PEDAL WENT TO THE FLOOR, AS I TRIED TO STOP FOR A LIGHT. HAD TO USE THE PARK BRAKE TO STOP. PRIOR TO THIS MY WIFE COMPLAIN SEVERAL TIME THAT THE PEDAL WAS SOFT AND WENT DOWN. WE COMPLAIN SEVERAL TIME ABOUT THAT AND THE ABS LIGHT COMING ON, ANSWER WE CAN NOT FINE ANYTHING. ON 01/10/07 THE ABS LIGHT DID NOT GO AWAY THEY REPLACED THE MASTER BRAKE CYL. NOT FIX THEY REPLACED ABS ACTUATOR ASSY FIX 12/10/09 BRAKE LIGHT AND ABS ON, BRAKE PEDAL TO THE FLOOR. *TR

I AM THE OWNER OF A 2001 TOYOTA PRIUS, PURCHASING THE CAR IN 2002. EVER SINCE I HAVE HAD IT, I HAVE NOTICED IT TEMPORARILY LOSES BRAKING AFTER DRIVING RELATIVELY SLOWLY -- 5 TO 20 MPH -- OVER A POTHOLE THAT HITS JUST ONE WHEEL. IT IS A RECURRING PROBLEM. I COMPLAINED TO THE DEALERSHIP IN 2002 AND WAS TOLD THAT THERE WAS NO PROBLEM AND THAT IT WAS PROBABLY THE WAY THE ANTI-LOCK BRAKE SYSTEM WORKED. I NOW KNOW THAT IF THERE IS A POTHOLE NEAR WHERE I WANT TO COME TO A STOP, I MAY HAVE TO LIFT MY FOOT OFF THE BRAKE AND THEN REAPPLY THE BRAKE WHEN GOING SLOW OR JUST PRESS HARDER ON THE BRAKE. IT DOES NOT HAPPEN THAT OFTEN, BUT IT DOES RECUR; WHILE I HAVE INDICATED A DATE IN ANOTHER FIELD OF THIS REPORT, IT IS TODAY'S DATE BECAUSE THE PROBLEM IS RECURRENT, ALTHOUGH PROBABLY NOT MORE OFTEN THAN A FEW TIMES PER YEAR, AND I CANNOT SAY WHEN IT LAST HAPPENED WITH ANY PRECISION. I AM NOW REPORTING THIS TO YOU BECAUSE I NOTICED AN ARTICLE IN THE NY TIMES REGARDING WHAT SOUNDS LIKE THIS VERY SAME PROBLEM. I HAVE NOT HAD ANY ACCIDENTS AS A RESULT OF THE PROBLEM. *TR
