The difference between the three parts of the brake shoe, the brake disc and the brake drum

    The brake shoe is an accessory that is pushed out by the action of the brake CAM or push rod, and is shaped like a half moon.
    Brake pads are also called brake pads. In automobile braking system, brake pad is the most critical safety components, all brake linings effect is good or bad are crucial, so good brakes is the patron saint of people and cars.
    Brake pads, brake lining) general by steel plate bonding, heat insulation layer and the friction blocks, steel to rust after coating, the coating process using SMT - 4 furnace temperature tracker to detect temperature distribution in the coating process to ensure quality. The thermal insulation layer is composed of non-heat transfer materials with the purpose of insulation. Friction block is composed of friction material and adhesives. The brake is pressed on the brake disc or the brake drum to produce friction, thus achieving the purpose of decelerating brake. Because of the friction, the friction block will gradually wear out, generally speaking, the lower the cost of the brake pad wear faster.
    The brake drum is a type of cast iron shaped like a tambourine, which is fixed with the tire and rotates at the same speed. When braking, apply oil pressure to push Brake Shoes to contact the inner edge of Brake drum, and the friction force produced by contact will be used to restrain the rotation of the tire to achieve the purpose of braking. The drum brake is composed of brake floor, brake pump, brake shoe and other related connecting rod, spring, pin and brake drum. At present only common use in rear wheel. The drum brake has lower cost and higher absolute power, and is used more in the rear wheels of small cars. However, the wear rate is higher, so the overall cost is higher.
