Brake Pad For Passenger Car 321698151B,191698151B,321698151H,321698151D for VOLKSWAGEN

The production process of brake pads mainly includes four aspects: raw material selection and cleaning, abrasive grinding, surface treatment, and finished product testing. ‌
The production process of brake pads is a complex and delicate process, and its quality directly affects the safety performance of automobiles. The following are the main steps in the production of brake pads:
Raw material selection and cleaning: Firstly, choosing high-quality raw materials is the key to ensuring the performance of brake pads. Raw materials need to be cleaned to remove impurities and ensure their purity.
Abrasive grinding: The friction material of brake pads needs to be ground to achieve the required hardness and wear resistance. This step is crucial for ensuring the performance of brake pads.
Surface treatment: The surface treatment of brake pads includes coating or other treatments to improve their corrosion resistance and thermal stability, while maintaining good friction performance.
Finished product testing: The produced brake pads need to undergo strict testing, including multiple indicators such as hardness, tensile strength, yield strength, etc., to ensure that their quality and performance meet the standards.
In addition, the manufacturing technology of brake pads has also reached a high level, including the use of high hardness alloys to manufacture friction lining layers, as well as ensuring structural stability and safety through stamping, welding, and rivet connections. The entire production process requires strict control of parameters such as temperature and pressure to ensure the performance and quality of brake pads.

Brake pads can generally be replaced before driving for 30000 to 50000 kilometers, and after driving for 60000 to 100000 kilometers. This replacement cycle is determined based on the general service life of the brake pads, but the specific replacement time will also be affected by factors such as the road conditions of the vehicle, personal driving habits, and the thickness of the brake pads. Therefore, the actual replacement cycle may vary. To ensure driving safety, it is recommended that car owners regularly check the thickness of the brake pads. Once the thickness of the brake pads is less than 3 millimeters, they should be replaced in a timely manner. In addition, the brake pad warning light on the vehicle dashboard is also an important reference indicator. When the brake pad warning light is on, it indicates that the brake pads have been worn to a certain extent and need to be checked in advance and may need to be replaced.
