What Does It Mean When the Brake System Warning Light Comes On?
2 Answers
The reasons for the brake system warning light coming on are as follows: 1. ABS function failure: The ABS mainly consists of the ECU control unit, wheel speed sensors, brake pressure regulation device, and brake control circuit. 2. Severe brake pad wear, leading to failure: As brake pads gradually thin during driving, the piston in the brake caliper adjusts the gap caused by wear. 3. Insufficient brake fluid: Most vehicles have a brake fluid level warning, and the brake fluid warning light usually shares the same indicator as the handbrake.
The brake system warning light is a serious alert signal, indicating potential brake failure. Common causes include low brake fluid level – requiring you to open the hood to check the reservoir, and add special brake fluid if it's below the minimum mark; severely worn brake pads – replace them immediately if you hear sharp noises or feel vibrations when braking; parking brake not fully released (though this usually has a separate indicator light); or faulty sensors triggering false alarms, especially on bumpy roads. As a driver with twenty years of experience, I always slow down and pull over immediately when this light comes on, avoiding high-risk areas like mountain roads or rainy conditions where braking distance increases and loss of control becomes likely. Visit a repair shop as soon as possible to have technicians use diagnostic tools to check the ABS system, hydraulic leaks, or wiring issues. Long-term neglect may damage the entire braking system, leading to costly repairs or even accidents. Safety must always come first – don't risk driving until the vehicle is properly repaired.
