What are the reasons for the brake light staying on after the engine is turned off?
1 Answers
After the engine is turned off, the brake light staying on is related to a faulty brake switch or a short circuit in the wiring. The specific reasons are as follows: Faulty Brake Switch: Manually replace the brake switch. Short Circuit in Wiring: Lack of brake fluid: Brake fluid plays a crucial role in the vehicle's braking system. When the driver presses the brake pedal, the force applied is transmitted by the piston in the master cylinder through the brake fluid to the wheel cylinders located at each wheel, causing the brake pads to contact the wheels and stop the vehicle. Damaged tail light bulb: The brake fluid reservoir has upper and lower lines. If the brake fluid level falls below the lower line, the sensor next to the reservoir will detect this and reflect it through the brake light on the dashboard. If the brake fluid level drops rapidly, it indicates a leak in the braking system. Brake pads need replacement: Note that if the parking brake is not released while driving, the light will also stay on. Therefore, first check whether the parking brake is released.
