id041100901500

1. Connect the SSTs to the brake pipes as shown in the figure.

2. Bleed the air from the brake system.

3. Measure the fluid pressure of the master cylinder and the rear brake.

  • If not within the specification, replace the dual proportioning valve.

Proportioning valve fluid pressure (without ABS (ABS/TCS) or DSC)

  Rear brake fluid pressure when front brake fluid pressure at 2,450 kPa {25 kgf/cm2, 355 psi}: 2,450 kPa {25 kgf/cm2, 355 psi} ± 200 kPa {2 kgf/cm2, 29 psi}
  Rear brake fluid pressure when front brake fluid pressure at 5,880 kPa {60 kgf/cm2, 853 psi}: 3,480 kPa {35.5 kgf/cm2, 505 psi} ± 300 kPa {3 kgf/cm2, 44 psi}
