The reasons for the brake warning light being on are: 1. Insufficient brake fluid. When the driver presses the brake pedal, the force applied is transmitted by the piston in the master cylinder to make the brake pads contact the wheels, thereby stopping the vehicle; 2. Damaged tail light bulb. The brake fluid reservoir has upper and lower level marks. When the brake fluid level drops below the lower mark, the sensor next to the reservoir detects this and triggers the brake warning light on the dashboard; 3. Severely worn brake pads. Brake pads come in two types: those with wear sensors and those without. Brake pads with wear sensors will automatically complete a circuit when worn to the limit, triggering the warning light. Brake pads without sensors won't trigger an automatic warning but will produce a metallic scraping sound to indicate they need replacement.
