Reasons for the brake system warning light to illuminate: 1. ABS function failure; 2. Severe wear or complete failure of brake pads; 3. Non-compliant brake fluid. Abnormalities in the brake system manifest as poor or ineffective braking, unilateral braking deviation, braking noise, brake drum overheating due to brake drag, or parking brake failure. The automotive brake system refers to a series of specialized devices that apply a certain force to specific parts of the vehicle (primarily the wheels) to enforce a certain degree of braking. The functions of the brake system are: to forcibly decelerate or even stop a moving vehicle as required by the driver; to ensure a stationary vehicle remains stable under various road conditions (including on slopes); and to maintain a stable speed for a vehicle moving downhill.
