2003 Toyota 4Runner service brakes, hydraulic problems

“TL* THE CONTACT OWNS A 2003 TOYOTA 4RUNNER. THE CONTACT STATED THAT THE VEHICLE STABILITY CONTROL SYSTEM AND THE TRACTION CONTROL SYSTEM WERE NOT FUNCTIONING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT REPAIR SHOP AND THE YAW SENSOR WAS RE-CALIBRATED. THE CONTACT WAS ALSO INFORMED THAT THE FAILURE COULD HAVE LED TO A BRAKE FAILURE IN WHICH THE BRAKES WOULD SEIZE. THE FAILURE RECURRED APPROXIMATELY THREE DAYS LATER. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 133,500.”

“2003 TOYOTA 4RUNNER HAS 3 FAULTY CALIPERS 2 ON FRONT AND ONE ON THE REAR. THE CALIPER USES A DUAL PISTON AND THE INTERIOR LOWER PISTON IS THE ONE THAT FAILED ON BOTH FRONT CALIPERS. THIS ISSUE IS KNOW TO THOUSANDS OF TOYOTA OWNERS WHO INQUIRE (ITS COMMON KNOWLEDGE AMONG THOSE WHO OWN THEM.) THE FACT THAT BOTH FAILED AT THE SAME TIME WAS INCREDIBLY DANGEROUS I LIVE IN THE MOUNTAINS AND LOSING BOTH FRONT BRAKES SIMULTANEOUSLY IS CAUSE FOR GREAT CONCERN MY SAFETY IS AT RISK AS WELL AS THE SAFETY OF MY PASSENGERS AND EVERYONE ELSE. I AM NOT SURE WHY IT HAS TAKEN SOO MUCH EFFORT FROM US (THE OWNERS OF SAID VEHICLES AND THEREFORE CALIPER) TO GET THIS LOOKED INTO. THE CALIPERS ARE OF A FAULTY DESIGN AND WILL FAIL PREMATURELY PUTTING HUMAN LIVES AT RISK. WHAT MORE DO YOU NEED? A PERSON TO DIE BEFORE THIS BECOMES CREDITED INFORMATION? JUST CHECK OUT T4R.ORG TO FIND ANY NUMBER OF IDENTICAL CLAIMS. *TR”

“TOOK VEHICLE IN FOR FRONT BRAKE REPLACEMENT AT 121,679 MILES. FIRST SET OF FRONT BRAKES WERE REPLACED AT 70,452 MILES. TECH CALLED TO INFORM ME THAT FRONT CALIPERS WERE FROZEN AND WOULD REQUIRE REPLACEMENT. SEEMS TO BE A RELATIVELY COMMON OCCURRENCE FOR HIGH MILEAGE 4 RUNNERS. SAME TIME HAD RIGHT AXLE BOOT REPLACED AS WELL. $1,118.00 FOR THE WHOLE JOB! OF COURSE I ALMOST KEELED OVER BUT HAD TO HAVE THE WORK DONE, AND WANTED DEALER TO PERFORM THE WORK SO I WOULDN'T HAVE ISSUES LATER IF ANYTHING WENT WRONG. HAVE HAD ALL WORK DONE AT THIS DEALER AND THEY'VE STOOD BEHIND ALL THEIR WORK, BUT WAS STILL A BIT DISAPPOINTED THAT THE FRONT CALIPERS WERE SHOT. CAR HAS ALWAYS BEEN GARAGE KEPT, AND KEPT CLEAN, INSIDE AND OUT. IN FACT, STILL LOOKS LIKE A NEW CAR. *TR”

“WHILE DRIVING FRONT ABS DOES NOT SEEM TO BE ACTIVATING. BRAKING DISTANCES WORSENED AS MY 03 4RUNNER WAS DRIVEN. IT TURNS OUT A PISTON IN THE BRAKE CALIPERS HAD FROZEN COSTING OVER $650 IN REPAIRS TO REPLACE THE CALIPERS. THIS IS A CONSTANT PROBLEM. MORE INFO CAN BE FOUND AT WWW.T4R.ORG. *TR”

“WHILE DRIVING I NOTICED THAT MY FRONT ABS WOULD NOT ACTIVATE IN AN EMERGENCY SITUATION. BRAKING DISTANCES BECAME A LOT LONGER. WHEN I WENT TO CHECK MY FRONT BRAKES, I DISCOVERED THAT THE FRONT LOWER BRAKE PISTON HAD FROZEN. IT WAS THE SAME FOR BOTH SIDES. TOOK IT INTO THE SHOP, AND THEY SAID THE SAME THING. THEY WANTED TO REPLACE THE CALIPER ON BOTH SIDES FOR A TOTAL OF $750. I DID IT MYSELF. THIS IS THE SAME THING THAT HAS HAPPENED TO MANY OTHER OWNERS, WHICH CAN BE FOUND ON WWW.T4R.ORG. *TR”

“BRAKES FAILED CAUSING ME TO RUN OFF THE ROAD ALMOST REAR ENDING ANOTHER VEHICLE. THE VSC, ABS AND BRAKE LIGHTS CAME UP ON THE DASH ALONG WITH AN AUDIBLE ALARM. REPAIR SHOP SAID BRAKES ARE FINE AND THAT IS A COMPUTER RELATED PROBLEM. *TR”
