Hydraulic brake system

The stand contains the brake system of VAZ-2109 including the brake master cylinder with vacuum booster, the rear wheel braking force regulator, the front wheel brake system of VAZ-2106 (with two working cylinders), the front wheel brake system of VAZ-2109 (with one working cylinder), the rear wheel brake system, the parking brake system.

Manometers measuring pressure in the working cylinders and a dynamometer measuring the brake pedal force formed by a loading gear are installed on the frontal panel of the stand. In the vacuum chamber rarefaction is formed by means of a vacuum pump.

The training system is supplied with a set of methodical and technical documentation for teaching staff.
