high pitch squeal with illumination of abs,vsc,brake lights
The problem is with the brake accumulator and master cylinder, power brake assembly on these 4runners. It is one of the few engineering failures I have seen Toyota make, and they do not seem to be interested in corrected the issue. Apparently, a 1.25 oring goes out internally on these units and causes a catastrophic failure of the braking system. The repair costs range from 1500 to 3000 dollars. It can result in a crash due to the brakes not stopping the vehicle. If you notice a squealing from under the dash or firewall or an intermittent squeal from the same area. STOP! Go immediately to a Toyota repair facility and have the brake system inspected. It WILL fail!
