Rear 350*28mm Type III Disc For Alfa Romeo Stelvio Quadrifoglio

According to the structure, the brake disc is divided into solid brake disc and ventilation disc. The solid brake disc is a metal disc used for braking and has no special structure. The ventilation disc is divided into two forms: marking disc and perforated disc. The functions of the two treatment methods are to improve the cooling performance of the brake disc, reduce its heat attenuation and provide better braking capacity.

The brake disc can be divided into carbon fiber ceramic brake disc and metal brake disc according to different materials. However, due to the high manufacturing cost of carbon fiber ceramic brake disc and the poor braking force at low temperature, although it has excellent heat attenuation resistance, it is still not selected by most vehicles. In order to increase the heat attenuation resistance, some manufacturers also treated the metal brake disc with carbon fiber to improve its ability in this regard, and avoid the poor low-temperature performance of carbon fiber ceramic material

Advantages of disc brake

1. The heat dissipation of disc brake is better than that of drum brake. When continuously stepping on the brake, it will not cause brake recession and brake failure.

2. The change of the size of the brake disc after heating does not increase the stroke of stepping on the brake pedal.

3. The disc brake system responds quickly and can do high-frequency braking action, so it is more in line with the requirements of ABS system.

4. Disc brake has no automatic braking effect of drum brake, so the braking force of left and right wheels is relatively average.

5. Due to the better drainage of the brake disc, the situation of poor braking caused by water or sediment can be reduced.

6. Compared with drum brake, disc brake has simple structure and easy maintenance.

Brake pads are also called brake skins. In the automobile braking system, the brake pad is the most critical safety part. The brake pad plays a decisive role in all braking effects. Therefore, a good brake pad is the protector of people and cars.

The brake pad is generally composed of steel plate, adhesive insulation layer and friction block. The steel plate shall be coated to prevent rust. Smt-4 furnace temperature tracker is used to detect the temperature distribution in the coating process to ensure the quality. The thermal insulation layer is composed of non heat transfer materials for thermal 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 braking. Due to friction, the friction block will be worn gradually. Generally speaking, the brake pad with lower cost will wear faster. After the friction materials are used, the brake pads shall be replaced in time, otherwise the steel plate will be in direct contact with the brake disc, which will eventually lose the braking effect and damage the brake disc.

How to buy Brake discs?

Before replacing the brake disc, first check whether the replaced brake disc is a pure accessory, whether the integrity of the product packaging, anti-counterfeiting marks and packaging marks are consistent with the marks on the brake disc, and whether the product model is consistent with the contents of the certificate. The brake discs produced by regular manufacturers are clearly packaged and printed, with license number, executive standard, etc. in the packaging box, there are certificate of conformity, production batch number, production date, etc. Using the brake disc with reliable quality can ensure its service life of 80000-120000 km. If you use fake or inferior brake discs, you can produce braking efficiency in a short time, but if you use them for a long time, the brake discs are easy to deform due to the high temperature caused by friction, reduce the braking effect, and finally affect the driving safety.
