D1935 Brake Pads

Carbon fiber ceramic brake pads

The valuable properties of carbon fiber are light weight and low density, but the strength is higher than that of steel. The high modulus of special carbon fiber is 6-8 times stronger than ordinary steel. And it has corrosion-resistant properties and is an important material in defense military and civilian use. Carbon fiber has the inherent characteristics of ordinary graphite materials, and has the softness and high tensile strength of fiber materials, which can be used for weaving and winding. The friction material using carbon fiber as the reinforcing fiber is not easily broken and wear-resistant, and the friction is stable at high temperature.

The carbon fiber ceramic brake pad adopts high-end high-quality raw materials such as aramid and copper fiber. A large number of optimization and matching between different materials play a synergistic effect, ensuring the reliability of the product design and the safety of use from the source. The hot pressing process of one molding is adopted to ensure the stability of various indexes such as hardness and density of the product. Matching the high-end silencer, greatly reducing the brake noise generation rate and improving the comfort of the brake.

Brake sheet fiber material

Asbestos has certain dangers to human health. In the process of mining or production, fine asbestos fibers are easy to fly into the lungs in the air. People who are in this environment for a long time are more likely to suffer from asbestosis. disease. Therefore, people began to look for other fiber materials that can replace asbestos to make friction materials, that is, non-asbestos friction materials or non-asbestos friction materials.

As the skeleton material of the friction material, the fiber plays an important role not only for the strength of the friction plate, but also for the performance of the friction plate. At present, in Europe and the United States and other developed countries and regions, it has begun to put more stringent requirements on the structure and physical and chemical properties of fibers, and lignocellulosic, inorganic whiskers (barium sulfate whiskers; calcium carbonate whiskers; potassium titanate whiskers, etc.) Mineral fiber, ceramic fiber, carbon fiber, various organic synthetic fibers, etc. give us a lot of choices, but from the perspective of cost and other comprehensive factors, crystal structure and water-soluble fiber materials will be the choice of our future friction materials.

Brake pad replacement timing

In the brake device of a car, the friction between the brake pad and the brake disc is mainly relied on. Automotive brake pads are an important safety component in automotive brake systems. Car brake pads are wearing parts and need to be replaced after a certain period of time or mileage. Therefore, we need to understand the timing of the replacement of the brake pads, and do not affect the normal use of the vehicle.

In normal use, when the difference in thickness between the brake pads on the fixed brake caliper reaches 1.5 mm, the difference between the thickness of the brake pads on the floating caliper reaches 3.0 mm. However, it is impossible to accurately determine whether the brake pad is worn or not by simple external observation. It is best to use a ruler to measure the thinnest part of the brake pad to see if it is within the allowable range. If you encounter some special circumstances, such as the brake pad is contaminated by oil or grease, and there are foreign objects in the brake pad, you need to replace the brake pad immediately, because the braking ability of the brake pad will be greatly reduced, and the brake safety will not be possible.
