[0002] The brake is a device that has the function of slowing down, stopping or keeping moving parts (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down the moving parts in the machinery. The service brake system of a car adopts a hydraulic transmission device, which is mainly composed of a brake master cylinder (brake master cylinder), hydraulic pipelines, brake wheel cylinders (brake slave cylinders) in the rear wheel drum brake, hydraulic cylinders in the front wheel caliper disc brake, etc. Among them, the brake master cylinder is also called the brake master oil (gas). Its main function is to push the brake fluid (or gas) to each brake slave cylinder to push the piston, providing power for the brake to achieve braking.
