(b) After the value for the bend point of oil pressure is determined, plot the performance line (a line parallel to
the valve unit performance line extending from the bend point of oil pressure), and read the rear wheel
cylinder oil pressure at the time when the front wheel cylinder pressure is at 10 MPa.
Ex: In the case where the bend point of oil pressure stands at 3.68 MPa, the standard value for rear wheel
cylinder oil pressure becomes 5.26 MPa, at the time when the front wheel cylinder pressure is at 10 MPa.

How to calculate standard oil pressure
When the break point (x) is known, the oil pressure in the rear wheel cylinder against that in the front
wheel oil cylinder is determined by the following equation:

Static Oil Pressure Split Point Curve
LSPV Performance Curve
Ex: Rear wheel cylinder oil pressure for front axle load of 10 MPa
Inclination x (X - Ps) + Ps = 0.25 x (10 - 3.68) + 3.68 = 5.26
