The free brake pedal pedal shall be between 8 and 10 mm. To measure it, it is necessary to set the line perpendicular to the floor and press the hand on the pedal until the brake is pressed.
If the resulting value is different from the regulation, the details of the pedal or vacuum amplifier may be worn or the vacuum amplifier shock or the distance from the pedal to the floor is not correct. The adjustment is made by means of a counterparty and a vacuum amplifier plug.
