Raise front brake pressure to 9,807 kPa (1,422 psi), 7,845 kPa (1,138 psi) And check rear brake pressure

Brake pressure chart in: kg/cm2 (psi,kPa)

NOTE: The brake pedal should not be depressed twice and/or returned while setting to the specified pressure. Read the value of rear pressure two
seconds after adjusting the specified fluid pressure.

Raise front brake pressure to 11,768 kPa (1,705 psi), 9,807 kPa (1,422 psi) AND CHECK REAR BRAKE PRESSURE

Brake pressure chart in: kg/cm2 (psi, kPa)

If necessary adjust the fluid pressure by changing the spring length.

-

Low pressure: Shorten A

-

High pressure: Lengthen A

-

Initial set length: 2VZ-EF 167.6 mm (6.598 in.) Others 166.9 mm (6.571 in.)

NOTE: 1 mm (0.04 in.) displacement of the spring length changes the fluid pressure about 98 kPa (14.2 psi).
