What are the reasons for the brake warning light to illuminate?
1 Answers
The reasons for the brake warning light to illuminate are as follows: 1. Insufficient brake fluid. When the driver applies the brakes, the brake fluid is compressed into the pipelines and brake calipers. If there is insufficient brake fluid, the brake fluid level sensor will detect it and alert the driver through the warning light. 2. Brake pads worn to the limit. Some vehicles are equipped with brake pad warning circuits by the manufacturer, which alert the driver when the brake pads are worn to their limit. 3. Short circuit in the brake warning light circuit. A multimeter can be used to measure whether the brake pad warning circuits for all four wheels, the brake fluid level sensor circuit, and the handbrake switch circuit are short-circuited.
