To what extent do the brake pads need to be replaced? What is the best material for the brake pads?

Brake pads are made of various materials, but most car owners don’t know much about brake pads, and it is often difficult to choose the brake pads that suit them. So what is the best material for brake pads?

Brake pads are generally composed of bonding insulation layers, friction blocks, steel plates, and these materials. The materials are mainly noa, metal, carbon, ceramics, etc. Now most of the brake pads on the market are made of metal and ceramic materials, and the owner needs to choose according to the actual situation.

Ordinary cars use metal brake pads, of which semi-metal brakes are more common. Because semi-metal brake pads have better heat resistance, higher power absorption per unit area, and relatively larger thermal conductivity, they can usually be applied to the braking work requirements of automobiles when running at high speeds or heavy loads.

Compared with metal brake pads, ceramic brake pads have better performance, because ceramics are harder and wear-resistant than metal, have higher thermal stability and lower thermal conductivity, so they are generally used in high-performance sports cars.

Brake pads are consumables. During daily driving, braking is often required. Brake wear will reduce the thickness of the brake pads. The thickness of the brake pads has a great influence on the braking effect. The thinner the brake pads, the worse the braking effect and the longer the braking distance. Longer and more unable to stop the car. Therefore, it needs to be replaced regularly. So, to what extent do the brake pads need to be replaced?

The thickness of the new brake pads is about 1.5 cm. As the car brakes during use, the thickness will be reduced by friction. Generally, the thickness of the brake pads is about two or three millimeters. If the thickness of the brake pads is less than 5 mm, it needs to be replaced in time. If you feel that the brake pedal is light or the brakes are hard, it also indicates that the thickness of the brake pads is not enough and needs to be checked and replaced in time.

Brake pads are generally checked every 3,000 kilometers, and need to be replaced every 30,000 to 40,000 kilometers, but the specifics should be determined according to the actual use and personal driving habits. Generally, there is an alarm pad on the brake pad, if the thickness is not enough, it will wear There will be a display on the dashboard of the car. To develop the habit of regular inspection, for the newly replaced brake pads, it needs to go through a certain running-in period in order to effectively maximize its braking effect.
