What is the structure of the brake pads

The insulation layer is composed of non heat transfer materials, with the purpose of insulation. The friction block is composed of friction materials and adhesives, which are compressed onto the brake disc or drum during braking to generate friction, thereby achieving the goal of vehicle deceleration and braking. Due to friction, the friction blocks will gradually wear out, and generally speaking, brake pads with lower costs will wear out faster. After using the friction material, the brake pads should be replaced in a timely manner, otherwise the steel plate will come into direct contact with the brake disc, ultimately losing the braking effect and damaging the brake disc.
