Why does the brake warning light come on when the brakes are working normally?
1 Answers
The brake warning light may come on while the brakes are functioning normally, possibly due to low brake fluid level. There are several reasons why the brake warning light may illuminate: 1. Severely worn brake pads: Brake pads come in two types - those with sensor wires and those without. Brake pads with sensor wires will automatically complete a circuit when worn to their limit, triggering the warning light. Brake pads without sensor wires won't trigger an automatic warning, but you'll hear a metallic scraping sound during braking. In this case, the brake pads need replacement. 2. Low brake fluid level: Brake fluid plays a crucial role in a vehicle's braking system. When the driver presses the brake pedal, the force is transmitted by the master cylinder piston through the brake fluid to the wheel cylinders at each wheel, causing the brake pads to contact the wheels and stop the vehicle. Insufficient brake fluid may also cause reduced braking power, and in severe cases, complete brake failure. This situation can be resolved by promptly replenishing the brake fluid.
