Why are the brakes on my Lexus not working?
For some time now there have been issues with brake actuators in several Lexus models failing. Not only does this mean that the brakes fail to perform as expected, but it can happen at seemingly random times, even at high speeds.
How does the brake actuator in a Lexus work?
It includes the pump motor, linear solenoid valve, accumulator, wheel cylinder, and master cylinder pressure sensors. When you apply pressure to the brake pedal, the fluid in the brake lines cause the actuator to push the brake shoes outward against the brake drum. In disc brakes, the caliper is squeezed into the brake pads.
Why does my Lexus make a loud noise when I brake?
The loud sounds likely result from the pressure leaking rapidly from the brake system, as the brake actuator fails to regulate the pressure. The worst and eventual result of brake actuator failure causes a sudden failure in the braking system.
