2. Start the engine and sharply release the depressed gas pedal to create the required vacuum in the vacuum path (0.75÷0.80 bar).
3. By depressing the brake pedal, release the vacuum to a depth of more than 0.80 bar.
4. Shut off the engine - the rate of vacuum loss should not exceed 0.4 bar/min. If necessary, check the operation of the vacuum booster servo (see Section Check of serviceability of functioning of the vacuum amplifier of brakes).
