Maintenance and care of passenger car brake discs

Regularly check for wear: Brake discs wear out over the course of use and generally need to be replaced when the thickness of the discs exceeds the specified limit.

Regularly check for wear: Brake discs wear out over the course of use and generally need to be replaced when the thickness of the discs exceeds the specified limit. The wear limit of brake discs varies from model to model, usually around 1 - 2mm. You can measure the thickness of your brake discs regularly with a professional measuring tool, such as a caliper, to determine the degree of wear.
Keep clean: The surface of the brake disk should be kept clean to avoid oil, dust and other impurities. Oil will reduce the friction between the brake pads and the brake disk, affecting the braking effect; dust and other impurities may aggravate the wear of the brake disk and brake pads. You can regularly wipe the surface of the brake disc with a clean, damp cloth to remove impurities.
Avoid frequent hard braking: Frequent hard braking will cause the brake disc to endure greater impact and friction, accelerating its wear. In daily driving, you should try to maintain a smooth driving habit, anticipate road conditions in advance, and reduce unnecessary emergency braking.
Pay attention to heat dissipation: When braking continuously for a long time or after braking at high speed, the brake disc will generate a lot of heat. At this time, you should avoid stopping the car immediately or rinsing the brake disc directly with water, so as to avoid deformation or cracking of the brake disc due to thermal stress. You can let the vehicle drive for a certain distance, so that the brake disc natural heat dissipation.
