Semi-metallic brake pads are brake pads that are generally composed of iron liners and friction materials. Do not wait for the friction material to wear away before replacing the shoe. The shoes that have reached the limit of use must be replaced, even if they can still be used for a period of time, the effect of braking will be reduced and the safety of driving will be affected.

The key to how brakes work is friction. With the help of friction between the semi-metallic brake pads and the brake disc (drum) and the tire and the ground, the kinetic energy of the car is converted into heat energy after friction, and the car stops. A good and effective braking system must be able to provide stable, sufficient and adjustable braking force, and have good hydraulic transmission and heat dissipation capabilities, so as to ensure that the force exerted by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder and Each auxiliary cylinder prevents hydraulic failure and brake drop due to high heat.
Semi-metallic brake pads replacement depends on how long your gaskets have been used in the life of your car. If most of you have driven more than 80,000 kilometers, the brake pads should be replaced. However, if you hear the wheels rubbing, you should basically replace the brake pads no matter how far you go. If you're not sure how many kilometers you've put on, you can go to a shop that replaces brake pads for free, buy them from them, or have them installed at an auto repair shop.
The advantage of semi-metallic brake pads is that they are cheap and wear-resistant, but they are prone to injury and make noise. If you want to know more, please continue to pay attention to this website.
