1. Connect the SSTs to the brake pipes as shown in the figure.
2. Bleed the air from the brake system and the SSTs. (Bleed the air from the SSTs through air bleeding valve A.)
3. Measure the fluid pressure of the master cylinder and the rear brake.
If not within the specification, replace the dual proportioning valve.
Dual proportioning valve fluid pressure
MASTER CYLINDER PRESSURE
(kPa {kgf/cm2, psi})
REAR BRAKE PRESSURE
(kPa {kgf/cm2, psi})
A: 3,430 {34.98, 497.5}
A": 3,130 {31.92, 453.9} — 3,730 {38.04, 540.9}
B: 5,880 {59.96, 852.8}
B": 4,010 {40.90, 581.7} — 4,810 {49.05, 697.6}
