Brake system failure refers to a problem with the brake system in a car.

There are several reasons that can cause a brake system failure: 1. Not enough brake fluid; 2. Air in the brake system; 3. Too much free travel or too large a gap between the brake pads, or the pads are worn, or there is dirt on them; 4. Blockages in the brake system's pipes; 5. Brake pads worn to the thinnest point.

To solve a brake system failure, it is recommended to contact a 4S store or a professional repair shop to check and fix the problem.

The brake system is a set of special devices that make it possible for a car to slow down or stop, or to maintain a stable speed while going downhill, or to keep a stopped car from moving. The system consists of a power supply, a control unit, a transmission system, and a brake. Since different models have different designs and different types of brakes, brake system failures can occur for many reasons.
