Checking the operation of the brake drive pressure regulator (Opel Kadett E)

Connect two pressure gauges in such a way that they can be used to read the pressure in the brake mechanisms of the front and rear wheels with a diagonal division of the hydraulic drive.

Press the brake pedal sharply several times to create the required pressure values (see subsection "Design and technical characteristics") in the hydraulic circuit of the front wheel brakes. Stop pressing the brake pedal as soon as the specified pressures are reached.

Check the pressure values in the hydraulic circuit of the rear brakes using a pressure gauge and, if they do not correspond to the specified values, replace the pressure regulators on hatchback and sedan vehicles, and adjust the pressure regulator on station wagons: if the pressure is too high, loosen the tension spring and vice versa.
