خرابی لاستیک ضربه‌گیر پدال ترمز

The small rubber pad the brake pedal rests against, perished or missing. It is what holds the brake light switch open when the pedal is released, so when it crumbles the switch closes and the vehicle believes the brake is permanently applied.

The consequences are out of all proportion to the part. Brake lights on constantly, cruise control that will not engage, a selector that will not leave park, and the engine module reducing torque because it believes the brake is being used. A vehicle with several unrelated faults and brake lights that never go out is this, and the part costs almost nothing. Look behind the pedal for a missing pad or its crumbs on the carpet before diagnosing any of the systems it has upset.
