The high brake light is faulty.
The high brake light failure light usually indicates that there is a problem with the high brake light system of the vehicle, which may be caused by a variety of reasons, including but not limited to brake pad wear, brake oil level is too low, brake system oil leakage, ABS function failure, electronic control system failure. These problems will not only affect the normal operation of the vehicle, but also may pose a potential threat to driving safety, therefore, when the high brake light fault light on, the driver should take immediate measures to check and repair.
Reason why the high brake light is on
Brake pads wear seriously: When the brake pads with induction line wear to the limit position, the induction line will automatically switch on the circuit and trigger the fault light.
Brake oil level is too low: If the brake fluid is missing, it will lead to a significant lack of braking force, or even loss of braking force, when the warning light will be lit.
Brake system oil leakage: oil leakage will lead to the waste of lubricating oil and fuel, consume power, affect the cleanliness of the car, but also cause environmental pollution, when the fault light will be lit.
ABS function failure: ABS (anti-lock brake system) function failure may also cause the high brake light fault light on.
Failure of the electronic control system: The vehicle's electronic control system may malfunction, causing the brake light signal to be incorrectly transmitted continuously.
