Frequently Asked Questions
What is a brake pedal stopper pad?
It is a small rubber or plastic bumper on the brake pedal arm that contacts the brake light switch. When it breaks, the pedal pushes the switch too far, causing brake lights to stay on.
Why does cruise control stop working with a brake switch issue?
Cruise control uses the brake switch signal to deactivate when the brake is pressed. If the switch is faulty, the system may think the brake is always applied and refuse to engage.
Is the stopper pad a common failure?
Yes. The stopper pad is a very common failure, especially on Toyota and Lexus vehicles. It is an inexpensive part and easy to replace, usually without any tools.
