What are the differences 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 and exert braking effect. Its shape is like a half-moon shape.
Brake pads are also called brake pads. In the car's braking system, brake pads are the most critical safety parts. The brake pads play a decisive role in all braking effects. Therefore, good brake pads are the protectors of people and cars.
Brake lining is generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be painted to prevent rust. During the coating process, an SMT-4 furnace temperature tracker is used to detect the temperature distribution during the coating process to ensure quality. The thermal insulation layer is composed of materials that do not conduct heat, and its purpose is to insulate. The friction block is composed of friction material and adhesive. When braking, it is squeezed on the brake disc or brake drum to generate friction, thereby achieving the purpose of decelerating and braking the vehicle. Due to friction, the friction pad will gradually be worn. Generally speaking, the lower the cost of the brake pad, the faster it will wear.
The brake drum is a cast iron piece 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. The friction generated by the contact inhibits the rotation of the tire to achieve the purpose of braking. Drum brakes are composed of brake base plates, brake cylinders, brake shoes and other related connecting rods, springs, pins, and brake drums. Currently only commonly used on rear wheels. Drum brakes have lower cost and higher absolute braking force, and are mostly used in the rear wheels of small cars. However, its wear rate is higher, so the overall cost is higher at the same time.
