[0002] Automobile braking refers to the braking technology that uses brakes to slow down or stop a car while it is driving. Common disc brakes are controlled by hydraulics. The main components include brake discs, slave cylinders, brake calipers, oil pipes, etc. The piston of the slave cylinder is acted upon by the hydraulic pressure transmitted by the oil pipe, pushing the friction pad against the brake disc to produce friction braking.

[0003] When in use, the oil pipe transfers the brake fluid of the master cylinder to the brake cylinder in the active suspension assembly. The automobile brake oil pipe joint is a component connecting the oil pipe and the master cylinder. The automobile brake oil pipe joint can be divided into hard pipe joints and hose joints according to the material.
