Connect control pressure gauges as when adjusting a pressure regulator.
Purge air from both gauge hoses through gauge vent screws.
Press the brake pedal until the pressure gauge connected to the front wheel brake shows a pressure of 100 kg/cm2.
Hold this pressure for 5 s. During this time, the readings of the pressure gauge connected to the brake mechanism of the rear wheel may change by no more than 10 kg / cm2. If the pressure has changed by a large amount, replace the pressure regulator.
