Connect two pressure gauges to the inlet and outlet of the pressure regulator respectively as shown in the figure.
Bleed the brake hydraulic system and pressure gauges.
While gently depressing the brake pedal, take the following measurements and ensure that the results are within the tolerance range.
The outlet pressure begins to drop relative to the inlet pressure (turn-on point).

Nominal value: 2.7–3.19 MPa
Check and ensure that when the brake pedal pressure increases, the fluid pressure at the outlet is within the specified limits, while the pressure at the inlet corresponds to the values given in the table.
Nominal value: 3.68–4.17 MPa.
The difference in pressure at the outlet between the right and left circuits of the hydraulic system.
Maximum allowable value: 0.39 MPa.
If the pressure measurement results do not correspond to the nominal values, replace the pressure regulator.
