SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:ROTOR
THE BRAKING SYSTEM ON MY 2000 TOYOTA TUNDRA, AS WELL AS THOSE OF NUMEROUS OTHER TUNDRA OWNERS, HAS AN INHERENT DESIGN FLAW THAT TOYOTA HAS CHOSEN TO IGNORE AND NOT INFORM US ABOUT. IN ADDITION TO THE FRONT BRAKES PULSATING AND FAILING TO STOP THE VEHICLE EFFECTIVELY, THE PROPORTIONING VALVE THAT TRANSFERS BRAKING FORCE TO THE REAR DRUM BRAKES DOESN'T SEEM TO WORK AT ALL. THERE IS A "LOAD SENSING DEVICE" THAT IS SUPPOSED TO INCREASE BRAKING FORCES TO THE REAR DRUMS WHEN THERE IS A LOAD IN THE TRUCK OR WHEN SOMETHING IS BEING TOWED BEHIND THE TRUCK. THIS DEVICE IS APPARENTLY NOT FUNCTIONING PROPERLY AS THE REAR PADS ON MY TRUCK DON'T APPEAR TO BE WORN MUCH AT ALL. THIS HAS CAUSED PROBLEMS AND ACCIDENTS FOR SEVERAL PEOPLE THAT OWN THIS VEHICLE AS EVIDENCED BY THE COMPLAINTS AT WWW.CONSUMERAFFAIRS.COM/AUTOMOTIVE/TOYOTA_TUNDRA_BRAKES.HTML. PLEASE HELP TO STOP THESE INCIDENTS BY FORCING TOYOTA TO ISSUE A RECALL ON THIS VEHICLE. *NM

TRUCK GETS A BUMP AFTER COMING TO A STOP. SOMETIMES IT'S GETS A REALLY HARD BUMP AND SOMETIMES IT'S JUST A LITTLE BUMP. I KEPT THINKING I GOT HIT AS IT IS VERY NOTICEABLE. NO ONE SEEMS TO KNOW WHY, BUT I DO KNOW THIS, IT ONLY HAPPENS WHEN THE A/C IS RUNNING. I BELIEVE IT'S A COMPUTER SOFTWARE PROBLEM. IT TOOK A COUPLE OF YEARS BECAUSE I FOUND OUT IT ONLY HAPPENS WHEN THE WEATHER GETS WARM AND I USE THE A/C. SEEMS LIKE QUITE A FEW PEOPLE ARE HAVING THE SAME PROBLEM AND THE DEALER IS SAYING "I DON'T KNOW ANYTHING" BECAUSE THEY CAN'T DUPLICATE THE PROBLEM, HOWEVER I SEEM TO BE ABLE TO DUPLICATE IT ALL THE TIME. *JS
