What are the reasons for the brake light staying on?
1 Answers
There are three possible reasons why a car's brake light stays on: 1. Lack of brake fluid, which is an indispensable part of the car's braking system. When the driver steps on the brake pedal, the force applied to the pedal is transmitted by the piston of the master cylinder through the brake fluid to the brake cylinders located at each wheel, causing the brake pads to contact the wheels and stop the vehicle. 2. The tail light bulb is damaged. The brake fluid reservoir has upper and lower limits. When the brake fluid level falls below the lower limit, the sensor next to the reservoir detects this and reflects it through the brake light on the dashboard. If the brake fluid decreases rapidly, it indicates a leak in the braking system. 3. The brake pads need replacement. Note that if the hand brake is not released while driving, the light will also stay on.
