The pipeline is a very important part of the braking system. This item consists of tubes. Together with the high-pressure pipelines, their function is to provide a connection of brakes and the brake master cylinder. If using a non-technical language, this spare part consists of flexible connections between the fixed parts of the car. When the driver presses the brake pedal, the load is transmitted to the amplifier, which creates an extra pressure on the main brake cylinder. As for the cylinder piston, it pumps fluid to the wheel cylinder through the pipeline. Consequently, the fluid pressure gets increased in the brake actuator. Apart from that, the wheel cylinders pistons have the option to move the brake pads towards the brake discs.

When the braking process is over (meaning when the driver releases the brake pedal), the pedal takes its original position under the influence of the return spring. At the same time, the piston of the brake master cylinder returns to its original position and the disk pads are discharged by the spring elements. In consequence, the brake fluid is displaced into the brake master cylinder from the wheel cylinder via the pipeline, and the pressure in the system drops. If you decided to replace the pipe yourself, it's not very simple. The difficulty lies not only in the scheme of details, but also in the availability of special equipment. First the car must be lifted up; the pipeline must be unscrewed and dismantled on the caliper or on the wheel brake cylinder.

To keep it simple, it is better to entrust the replacement of parts on your car to experts in a repair-shop.
