Problems solved by technology

[0002] At present, the brake pads of the automobile disc brake system will be coated with ordinary lithium-based grease on these parts during assembly and maintenance. Due to the poor temperature resistance and anti-wear performance of ordinary lithium-based grease, there will be the following problems: use The temperature is low, generally not exceeding 120°C. Ordinary lithium-based grease will quickly become thinner and lost at high temperature, which does not play a role in improving safety performance. Some may drip on the brake disc after high temperature. It will slip, causing serious safety hazards and causing serious losses to life and property.
The brake pad silencer products supplied by many domestic brake pad export manufacturers are all because the domestic silencer products cannot meet the requirements of Europe and the United States, so they are forced to use expensive imported silencer products.
