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.
