Brake Drum Wheel Cylinder Problems of Toyota RAV4

On October 5 and 6, 2015 my 2008 Toyota Rav4 was in for service at piercey Toyota in milpitas to replace all four tires, front/back brakes and front shock absorbers, a total of $2,000. On October 8, 2015, while I was driving my car back from stanford lucile packard over dumbarton bridge, I have noticed that my brakes would not engage and I could not slow down my car. Just before this event, the abs, vsc, and slip warning lights all came on. The brake pedal felt very stiff and I was not able to do any repetitive pumping of the brake. I called 911 and requested assistance. When the front traffic came to a hold I had to use my emergency brake and my entire car slipped to the left. We almost got hit by the bus behind us. Some good samaritans saw what happened and helped me to get my car off the road. That day, my 9 yrs. Old son and I could have been killed. I request that Toyota investigates/recalls the brake actuator assemblies for Toyota Rav4 2008. In the subject vehicles, the brake system contains a brake actuator that adjusts the fluid pressure of each wheel cylinder. Within the actuator is an electrical terminal that connects the brake actuator motor and the circuit board of the skid control electronic control unit (ecu). Due to manufacturing variation, there could be a reduction in contact force between the two components of the terminal, causing oxide film to increase resistance. A larger than normal increase in resistance can cause the illumination of various warning lights, including those for the skid control (vehicle stability control or vsc) system, antilock brake system (abs), and traction control system. Lfthis occurs, these systems could become inoperative, which could increase the risk of a crash.

The contact owns a 2008 Toyota Rav4. The contact stated that while exiting a parking space, he attempted to engage the brakes but the brake pedal abnormally traveled to the floorboard. The failure was also experienced a second time and the contact had to engage the emergency in order to stop the vehicle. The vehicle was taken to the dealer. The technician diagnosed that the brake cylinder and the rear passenger caliper malfunctioned. As a result of the failure, both parts needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was repaired. The failure mileage was 79,000 and the current mileage was 79,030.
