2001 Toyota 4runner Brakes Problems

BRAKE PEDAL PULSATION DUE TO FRONT BRAKE ROTORS. REPLACED PADS AND TURNED ROTORS AND PROBLEM WAS GONE FOR THREE TO FOUR WEEKS. PROBLEM CAME BACK. PROBLEM HAS OCCURRED PERSISTENTLY FOR OVER 100K MILES. I AM THE SECOND OWNER, PURCHASED AT 32K IN 2003. *TR

ON THE EVENING OF 2-4-10, I WAS TRAVELING ON AN ANGLED, CURVED, ON-RAMP TO A FREEWAY, WHEN THE VSC (VEHICLE SKID CONTROL) SUDDENLY AND AUTOMATICALLY APPLIED THE VEHICLE BRAKES. THE VEHICLE SPEED WAS APPROX. THE RECOMMENDED SPEED FOR THE TURN. THE CONDITIONS WERE WET, AS IT HAD BEEN RAINING OFF AND ON ALL DAY. A BEEPING SOUND WAS HEARD, AND SIMULTANEOUSLY THE VEHICLE LOST TRACTION, AND TRAVELED IN A TANGENT/STRAIGHT DIRECTION TO THE CURVED ON-RAMP. I HAD ZERO CONTROL OF THE VEHICLE FOR ~3 LONG SECONDS, AND ENDED UP SIDEWAYS ON THE SHOULDER OF THE ROAD. LUCKILY, NO ONE WAS HURT NOR CLOSE BY. THIS COULD EASILY HAPPEN ON A YIELD TURN, CAUSING A BLIND-SIDED T-BONE COLLISION, OR REAR-ENDED COLLISION. THIS FAULTY SYSTEM NEEDS IMMEDIATE FIXING, AND SHOULD BE CONSIDERED AN EXTREME SAFETY HAZARD. *TR

I WAS DRIVING A 2001 TOYOTA 4RUNNER ON A 2 LANE MOUNTAIN HIGHWAY A COUPLE YEARS AGO. WINTERTIME, WET ROAD. GOING 50 MPH AROUND A WIDE RIGHT TURN, THE ANTI-SKID BRAKE SYSTEM SUDDENLY SCREECHED AT ME, AND APPARENTLY APPLIED THE BRAKES ON THE LEFT SIDE OF THE CAR, CAUSING IT TO SWERVE LEFT TOWARDS THE OPPOSING LANE OF TRAFFIC. I MANAGED TO CORRECT, AND AVOID AN ACCIDENT. I WENT WITH MY FRIEND WHOSE CAR IT WAS TO THE DEALER LATER AND DESCRIBED THE OCCURRENCE. THE DEALER CLAIMED THAT ONE OF THE TIRES WAS LOW. I NEVER TRUST ANTI-SKID BRAKE SYSTEMS SINCE THIS OCCURRENCE. THIS KIND OF RESPONSE IS COMPLETELY UNACCEPTABLE. THAT SAME CAR ALSO HAD A FIRMWARE GLITCH IN THE 4 WHEEL SYSTEM THAT WOULD CAUSE THE 4 WHEEL NOT TO BE DISABLED UNTIL YOU PULLED OVER AND SHUT OFF THE ENGINE FOR A BIT, ON AN UNFREQUENTED BASIS. *TR

2001 TOYOTA 4 RUNNER 4WD WHILE SPEED 30 TO 40 MPH DRIVING IN A SLOW RIGHT BANK ( NOT A CURVE) HEAR LOW BEEP NOISE SKID LITE ICON COMES ON AND AS IF TRUCK TOOK OVER I LOST STEERING , BRAKES AND POWER . BRAKES WERE ACTIVATING ON THEIR OWN AND THE TRUCK PROCEDED ACROSS YELLOW LINE INTO ONCOMING TRAFFIC!!! TOYOTA PULL CODES NOTHING SAID I MUST HAD PUT TRUCK IN A SKID . NO I DIDNOT PUT TRUCK INTO SKID. HAPPEN AGAIN THIS TIME WIFE FOLLOWING ME AND SHE WITNESS IT ALSO . SHE SAID IT WAS AS IF I WAS STEERING IT INTO ONCOMING TRAFFIC. *TR

VERY STRONG VIBRATION/SHAKING FELT WHEN BRAKING HARD OR DOWNHILL. ROTORS AND BRAKES ARE GOOD. *NM

WHILE DRIVING CONSUMER HEARD A BEEPING NOISE AND THE TRACTION CONTROL WARNING LIGHT ILLUMINATED. ALL 4 WHEELS THEN LOCKED UP SIMULTANEOUSLY WHICH CAUSED VEHICLE TO SWERVE, ALMOST COLLIDING WITH OTHER VEHICLES. PROBLEM OCCURRED SEVERAL TIMES DURING TRIP. DEALER DIAGNOSED THAT THE YAW CONTROL SENSOR MALFUNCTIONED, WHICH CAUSED THE VEHICLE TO THINK IT WAS FLIPPING OVER, THUS TAKING CONTROL OF VEHICLE.*JB

WHEN APPLYING BRAKES AT A SUDDEN/ EMERGENCY STOP VEHICLE WOULD SLIDE OR SKID BEFORE STOPPING. DEALER NOTIFIED. FEEL FREE TO PROVIDE ANY FURTHER DETAILS ON THIS MATTER. *AK

BRAKE PEDAL IS OF SUCH DESIGN THAT WHEN APPLYING BRAKES CONSUMER HAS TO TURN FOOT SIDEWAYS TO GET PEDAL TO DEPRESS. ARM THAT ATTACHES TO PEDAL GOES UPWARD, AND IS IN THE WAY WHEN APPLYING BRAKE. CONSUMER HAS CONTACTED TOYOTA, WAS TOLD TO CONTACT DEALER. *AK
