Brake pads are a life-critical component for cars and occupants. A car must run fast and stop, and brake pads are among the most neglected, but most important components. How big is the horsepower? Not stopping is just a killing machine.
The working principle of the automobile brake parts is believed to be clear to everyone. When the brake pedal is depressed, the master cylinder will build up pressure in the brake oil circuit. Pressure is transmitted to the piston on the caliper via the brake fluid. After the piston is pressurized, the brake pad is pressed to clamp the brake disc or the brake drum, causing the brake pad to friction with the brake disc to reduce the rotational speed of the wheel to stop the vehicle.
From the principle we can see that the brake pads play an important role. A brake pad is mainly composed of the following components: a metal base plate, a heat insulation layer, and a friction pad. The metal bottom plate also has the effects of reducing noise and shock absorption.
The purpose of the heat insulation layer is to prevent a large amount of heat generated during brake friction from being transmitted to the brake oil circuit, causing the temperature of the brake oil to rise, and causing bubbles to affect the effect. The friction block is responsible for friction friction with the brake disc, composed of friction material and adhesive.
