Bull brake pad are equipped with premium brake shims, we have different kinds of brake shims, as showed in pictures, they are made up of thin metal, rubber or fabric, which adhesive pads that fit between the brake pad and the brake caliper to correct small differences that sometimes lead to noise. These brake shims are mainly used to keep the noise down and any rattles to a minimum. Not all brake pads come with shims as they aren't required and function perfectly without needing them.

The tribological application of phenolic resin-basd friction materials is usually limited owing to the relatively poor stability and wear resistance. Therefore, we choose to incorporate various reinforcing and filling constituents such as steel fibers, copper fibers, carbon fibers, Dupont aramid, and ceramic fibers, mineral wool, carbon coke, etc into phenolic resin-based friction composites for the purpose of increasing the stability and wear resistance.

Bull brake backing plates are produced by high quality steel, which has a strong ability to hold the braking system together so it can work properly; the friction materials are attached to one side of the brake backing plate. Our brake backing plates are all meet the international standards, including the hardness, smoothness, and thickness, which will give a steady and comfortable braking; it can make you safe all the way along.
