The Type Of Brake Pads Are More
Brake pads are the key components of the brake system, the name of the brake lining or friction film, it is a car in the goods of the wearing parts, brake pads installed inside the caliper, when depressing the brake, the brake oil from the brake tubing Press the hydraulic chamber, to promote the piston and calipers in the opposite direction of movement, the piston to promote the main brake pads and calipers driven by the brake pads at the same time squeeze the brake disc. Friction to the brake disc (connected with the tire, nonsense! Sorry!) Slow down, Brake Pad and finally stopped. In fact, no matter what type of brake, is a mechanical energy into the process of thermal energy. Brake when the brake pads and the temperature of the dish will be extremely high.
Brake pads are also called brake pads. In the car's braking system, the brake pads are the most critical safety parts, all the braking effect is good or bad brake pads play a decisive role, Brake Pad so that good brake pads are the protection of God and the car. Brakes are generally made of steel, adhesive insulation and friction block, which is composed of non-heat transfer material, the purpose is to heat. The friction block is composed of friction material, adhesive, brake is squeezed in the brake disc or brake drum on the friction, so as to achieve the purpose of vehicle deceleration brake. Due to friction, the friction block will gradually be worn, in general, Brake Pad the lower the cost of the brake pads wear faster. After the use of friction material to replace the brake pads, or steel plate and brake disc will be in direct contact, and ultimately lose the braking effect and damage the brake disc.
The brake pads are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction lining and the friction lining are subjected to external pressure to produce a friction action to achieve the purpose of vehicle deceleration. Brake and brake disc replacement time cycle is not fixed, Brake Pad depending on the vehicle driving road conditions, the driver step on the brake pedal frequency and intensity. General conventional brake pad replacement mileage is about 25,000 -3 million km per ride.

Brake type
According to the brake different brake pads can be divided into: drum brake pads and disc brake brakes two, Brake Pad according to the material of different brake pads can be divided into asbestos type, semi-metal type, NAO type Asbestos organic type) brake pads and other three.
With the rapid development of modern technology, Brake Pad like other parts of the brake system, the brake pads themselves in recent years are constantly evolving and changing.
In the conventional manufacturing process, the friction material used on the brake pads is a mixture of a plurality of binders or additives, and the fibers are added thereto to enhance their strength and to reinforce. Brake manufacturers in the use of materials on the announcement, Brake Pad especially in the new formula is often tight-lipped, of course, some ingredients such as: mica, silica, rubber debris, etc. are open. The ultimate effect of brake pads, anti-wear, anti-temperature and other properties will depend on the relative proportions between the different components. The following is a simple talk about several different materials of the brake pads.
Asbestos type brake pads
Since the beginning of the asbestos has been used as brakes of the reinforcement material, asbestos fiber has high strength and high temperature characteristics, Brake Pad it can meet the brake pads and clutch discs and liner requirements. This fiber has a strong tensile strength, even with high-grade steel to match, and can withstand high temperatures of 316 ℃. More importantly, asbestos is relatively cheap, it is extracted from the amphibole ore, and this kind of ore in many countries has been a lot of discovery.
