The difference between brake shoes, brake pads and brake drums
The brake shoe refers to the accessory that is pushed outward by the action of the brake cam or push rod to suppress the brake drum to play the role of braking, and its shape is like a half-moon shape.
Brake pads are also called brake pads. In the braking system of the car, the brake pad is the most critical safety part, and all the braking effects are decisive for the brake pad, 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, steel plate to be coated to prevent rust, coating process with SMT-4 furnace temperature tracker to detect the temperature distribution of the coating process to ensure quality. The thermal insulation layer is composed of materials that do not transfer heat for the purpose of heat insulation. The friction block is composed of friction material and adhesive, and it is squeezed on the brake disc or brake drum to generate friction when braking, so as to achieve the purpose of vehicle deceleration braking. Due to friction, the friction block will gradually be worn, generally speaking, the lower the cost of the brake pad, the faster the wear.
A brake drum is a cast iron shaped like a tambourine that is fixed to a tire and rotates at the same speed. When braking, the oil 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 floor, brake sub-cylinder, brake shoe and other related connecting rods, springs, spikes, brake drums. At present, it is only commonly used in the rear wheels. Drum brakes are less expensive and have higher absolute braking power, and are more commonly used in the rear wheels of small cars. However, its high wear rate and therefore higher overall costs.
