What does excessive wear of brake pads mean?
1 Answers
Excessive wear of brake pads refers to a brake pad warning, usually indicating that the brake pads have reached their wear limit and need to be replaced promptly. Failure to do so may result in brake failure and damage to the brake disc. There is also a less common cause that can trigger an excessive wear warning for brake pads: when the brake pad wear sensor is damaged and an open circuit occurs, it may cause a false alarm, and the vehicle's dashboard will display an excessive wear warning for the brake pads. Below is relevant information: 1. Automobile brake pads: Automobile brake pads refer to the friction materials fixed on the rotating brake drum or brake disc of the wheel. The friction lining and friction blocks bear external pressure to generate friction, thereby achieving vehicle deceleration. Automobile brake pads are generally composed of steel plates, adhesive insulation layers, and friction blocks. The steel plates are coated to prevent rust, and the coating process is monitored using an SMT-4 furnace temperature tracker to ensure the temperature distribution during the coating process meets quality standards. 2. How brakes work: The working principle of brakes mainly relies on the friction between the brake pads and the brake disc (drum), as well as between the tires and the ground, to convert the kinetic energy of the moving vehicle into heat energy through friction, thereby stopping the vehicle. A good and efficient braking system must provide stable, sufficient, and controllable braking force, and have excellent hydraulic transmission and heat dissipation capabilities to ensure that the force applied by the driver on the brake pedal is effectively transmitted to the master cylinder and sub-cylinders, while avoiding hydraulic failure and brake fade caused by excessive heat.
