It is responsible for transmitting the brake fluid pressure generated by the master brake cylinder to the brake cylinders of each wheel, thereby realizing the braking function of the vehicle. The brake oil pipe plays a vital role in the brake system. They are usually divided into two parts: a hard pipe that does not need to be moved and a movable hose. The hard pipe part is generally made of a special metal pipe with high strength; the hose part is mostly made of a rubber hose containing nylon and metal wire mesh. This design allows the hose to adapt to the movement of the vehicle's movable suspension components and keep the transmission of brake fluid unimpeded.
