- Remove the master cylinder. (See «MASTER CYLINDER REMOVAL/INSTALLATION»(ref-244464-S03412757792006092400000).)
- Remove the clutch pipe. (MT)
- Remove the nut (Scheme 37), then remove the cooler hose (LO) bracket from the vehicle.
- Remove in the order indicated in (Scheme 36).
- Install in the reverse order of removal.
- After installation, perform brake pedal inspection. (See «BRAKE PEDAL INSPECTION»(ref-244464-S11006378782006092400000).)
Scheme 37
- Connect the SSTs to the brake pipes (Scheme 38)
- Bleed the air from the brake system and the SSTs. (Bleed the air from the SSTs through air bleeding valve A.)
- Measure the fluid pressure of the master cylinder and the rear brake. If not within the specification, replace the dual proportioning valve.

- Remove in the order indicated in (Scheme 40).
- Install in the reverse order of removal.
Scheme 40
- Place an alignment mark on the brake pipe and dual proportioning valve.
Scheme 41
- Install the dual proportioning valve so that the R marks faces the upper side of the vehicle.
Scheme 42
- Align the marks made before removal and install the brake pipe to the dual proportioning valve referring to see scheme 29.
