③ Measurement of hydraulic pressure
(a) Depress the brake pedal until the oil pressure in the front wheel cylinder reaches 5.9 Mpa, 7.8 Mpa.
· Don't depress the brake pedal a number of times.
· When the oil pressure in the front wheel cylinder exceeds 5.9 Mpa, 7.8 Mpa, release the pedal completely and
then depress it again
(b) After holding the oil pressure in the front wheel cylinder at (5.9 Mpa, 7.8 Mpa) for two seconds, measure the
oil pressure in the rear wheel cylinder.
Standard rear Iiquid pressure
Adjusted Standard Front liquid Pressure
5.9 Mpa
7.8 Mpa
④ How to determine standard oil pressure in rear wheel cylinder
Only in the case where the rear axle load can not be adjusted to a value shown as the standard axle load,
adjust the oil pressure in the rear wheel cylinder using the diagram shown below.
(a) Plotting the rear axle load along the abscissa of a static oil pressure curve bend point diagram, determine a
bend point of oil pressure.
Ex: For the rear axle load of 14701 N, the oil pressure bend point is 4.5 Mpa
See (3) Static oil pressure curve bend point diagram
