What is the difference between brake shoes, brake pads and brake drums?

Brake shoe refers to the brake CAM or push rod action and is pushed out to suppress the brake bulge back brake accessories, the shape of the answer such as half moon.

Brake pads are also called brake pads. In the brake system of the car, the brake pad is the key safety parts, all the brake effect is good or bad brake pad plays a decisive role, so a good brake pad is the protector of people and cars.

Brake lining is generally composed of steel plate, adhesive insulation layer and friction block, the steel plate is coated to prevent rust, the coating process with SMT-4 furnace temperature tracker to detect the temperature distribution of the coating process to ensure quality. The insulation layer is composed of non-heat transfer material, the purpose is to heat insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to produce friction, so as to achieve the purpose of vehicle deceleration and brake. Because of friction, friction block will gradually be worn, generally speaking, the lower the cost of brake pad wear faster.

A brake drum is a cast iron shaped like a tambourine that is fixed to the tire and rotates at the same speed. When braking, hydraulic pressure is used to push the Brake Shoes (Brake Shoes) to contact the inner edge of the Brake drum, and the friction force generated by the contact is used to suppress the rotation of the tire to achieve the purpose of braking. Drum brake is composed of brake bottom plate, brake sub pump, brake shoe and other related connecting rod, spring, pin and brake drum. At present, it is only commonly used in the rear wheel. Drum brakes, which have lower cost and higher absolute braking force, are widely used in the rear wheels of small cars. But its wear rate is higher, so the overall cost is higher at the same time.
