The difference between brake shoe, brake pad and brake drum

Brake shoe refers to an accessory that is pushed outward by the action amount of the brake cam or push rod to press the brake drum for braking, and its shape is like a half-moon shape.

    Brake pads are also called brake pads. In the brake system of a car, the brake pad is the most critical safety component. All brakes are good or bad because the brake pad plays a decisive role. Therefore, a good brake pad is the protector of people and cars.

    The brake lining is generally composed of a steel plate, an adhesive heat insulation layer and a friction block. The steel plate is painted to prevent rust. The coating process uses the SMT-4 furnace temperature tracker to detect the temperature distribution of the coating process to ensure quality. The heat insulation layer is composed of materials that do not transfer heat, and the purpose is heat insulation. The friction block is composed of friction material and adhesive. When braking, it is squeezed on the brake disc or brake drum to produce friction, so as to achieve the purpose of decelerating the vehicle. Due to friction, the friction pads will gradually wear out. Generally speaking, the lower the cost, the faster the brake pads wear.

    The brake drum is a cast iron shaped like a tambourine, it is fixed with the tire and rotates at the same speed. When braking, use oil pressure to push the brake shoes (Brake Shoes) to contact the inner edge of the brake drum. The friction force generated by the contact can inhibit the rotation of the tire to achieve the purpose of braking. The drum brake is composed of brake connecting plate, brake cylinder, brake shoes and other related connecting rods, springs, spikes, and brake drums. Currently only commonly used in the rear wheel. Drum brakes have lower costs and higher absolute braking power, and are used more frequently in the rear wheels of small cars. But its wear rate is higher, so the overall cost is higher at the same time.
