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. In order to save, buy the required parts in advance in our online store, before taking the car to repair. It is cheaper to acquire all the necessary spare parts, such as damper racks, radiator grilles or brake drums, in our online store. You can always count on quick delivery, within a few days.

What you need to know about vacuum brake booster hose: lifetime limits, common defects and their signs, tips and recommendations

The hose of the vacuum brake booster has no specific lifetime limit. Replacement of the part is mostly performed due to its tearing, deformation or cracking.

The main sign of hose defectiveness is hissing sound of the vacuum booster. Also, at this defect, resistance of the brake pedal increases. Moreover, at tearing or damaging of the hose, unstable operation of the engine occurs at high rpm, and vibration is noticeable in the cabin at braking.

For detailed diagnostics you’d better apply to a service station, as work with brake system elements requires high accuracy. Specialists will demount the vacuum booster, inspect its elements and check hermeticity of the whole brake system.

It is also recommended to perform replacement of the vacuum brake booster hose at a service station. Improper installation of the brake system elements may lead to its incorrect operation, and this is dangerous for life.
