Oil seal 03.7718-5016.1 of the vacuum brake booster

The most characteristic manifestation of the failure of the vacuum booster seal is the presence of sounds that resemble a hiss in the area where the brake pedal is located. This is a fairly common situation when this seal hardens due to sudden temperature changes, simply wears out, or is exposed to various working fluids and other external factors.

To quickly fix this problem, just order a new part in our online store and replace it. The repair process is not a difficult task. To perform the replacement, no special skills and knowledge are required, which will significantly save both your time and your money.

The spare part is made of a specially selected heavy-duty material to prevent its rapid wear, deformation and destruction under the influence of various loads and temperature changes. Due to the fact that all dimensions of the seat are saved in this part, it can be easily and with minimal time mounted in your car.
