Failure of automobile brake induction wire may lead to the following problems:

1. Brake system failure: The failure of the brake induction line will cause the brake system to fail to work normally, and the brake signal cannot be accurately transmitted to the electronic control unit of the vehicle, thus affecting the control and adjustment of the brake system, which may lead to brake failure or failure to slow down and stop normally.

2. Brake failure light is on: When the brake induction line fails, the vehicle's electronic control unit may detect abnormal signals or no signals, which will cause the brake failure light to be on, reminding the driver that there is a problem with the brake system and it needs to be repaired in time.

3. Abnormal noise of brake system: When the brake induction line fails, the brake system may not work normally, resulting in abnormal noise during braking, such as poor friction between brake pads and brake discs or insufficient brake fluid pressure.

4. Insensitive braking: The failure of the brake induction line will cause the brake system to be unable to accurately perceive the driver's braking intention and strength, which may lead to insensitive braking or slow response, and affect the braking performance and safety of the vehicle.

5. Brake system failure: If the brake induction line fails for a long time or is not repaired in time, it may cause the brake system to completely fail and fail to work normally, which will seriously affect the driving safety of the vehicle.

To sum up, the failure of the automobile brake induction wire may lead to the failure of the brake system, the lighting of the brake failure light, the abnormal noise of the brake system, the insensitivity of the brake and the failure of the brake system. Once there is a problem with the brake induction line, it should be repaired and maintained in time to ensure the normal operation and driving safety of the brake system.
