READ MOREBrake pad is the core safety component of the automobile braking system, and its performance determines the braking efficiency and driving safety of the vehicle. As the key medium for converting vehicle kinetic energy into thermal energy, it is a safety guarantee between the driver and the road.
The working principle of brake pad is based on friction mechanics. It converts vehicle kinetic energy into thermal energy by clamping the rotating brake disc or brake drum to generate friction. In this process, the performance of friction material is crucial. Brake pads are usually composed of steel plates, thermal insulation layers and friction blocks, among which friction materials have evolved from asbestos, semi-metal to ceramic composite materials. Asbestos materials have been eliminated due to poor safety performance. Semi-metal formulas are still widely used in economical vehicles due to their high friction coefficient and low cost, but their noise and wear problems always exist; ceramic brake pads have achieved breakthroughs in high temperature stability, quietness and wear resistance through the composite of carbon fiber and ceramic fiber, becoming the first choice for high-end models.
In actual use, brake pads require scientific maintenance. Under normal driving conditions, the front brake pads need to be tested for thickness every 30,000-50,000 kilometers and the rear brake pads every 40,000-60,000 kilometers. When the thickness of the friction material is less than 3 mm, it must be replaced. When replacing, a special tool must be used to reset the piston of the slave cylinder to avoid damaging the hydraulic system; after installation, a 200-kilometer run-in is required to ensure that the friction material and the brake disc are fully fitted.
