DUAL PROPORTIONING VALVE
DUAL PROPORTIONING VALVE
Removal and InstallationINFOID:0000000005928400
Removal
1. Remove the cowl top. Refer to EI-24, "Removal and Installation".
2. Disconnect brake lines from dual proportioning valve. • Mark brake lines for installation.
3. Remove dual proportioning valve bolt and dual proportioning valve.
4. Remove two bolts and bracket.
Installation
Installation is in the reverse order of removal.
• When installing brake lines to the dual proportioning valve, tighten to specifications. Refer to BR-11,
"Hydraulic Circuit".
InspectionINFOID:0000000005928401
CAUTION:
• Carefully monitor brake fluid level at master cylinder.
• Use the recommended new brake fluid. Refer to MA-14, "
Fluids and Lubricants".
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on paint areas, wash it away with water immediately.
1. Connect a suitable brake fluid pressure gauge to air bleeders of front and rear brakes on either LH and RH side.
2. Bleed air from the brake fluid pressure gauge.
3. Check fluid pressure specific ation by depressing the brake pedal.
• If output pressure is out of specification, replace the dual proportioning valve.
Unit: kPa (kg/cm2, psi)
4. Bleed air after disconnecting the brake fluid pressure gauge. Refer to BR-9, "Bleeding Brake System".

FRONT DISC BRAKE
• When installing pad retainer, attach it firmly so that it isnot lifted up from torque member, as shown.
4. Install cylinder body to torque member and apply rubber grease, then install lower sliding pin bolt (lower side) and tighten it to the
specified torque. Refer to BR-25, "
Component".
CAUTION:
Check the brake fluid level in the reservoir tank for fluid
level because brake fluid returns to master cylinder reser-
voir tank when pressing piston in.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily
press to piston in.
5. Check brakes for drag.
6. Install front wheel and tire. Refer to WT-7, "
Adjustment".
7. Check brake fluid level. Refer to BR-9, "
On Board Inspection".
CLZ25VF
Removal
1. Partially drain brake fluid from reservoir. refer to BR-9, "Drain and Refill".
2. Remove the front wheel and tire using power tool.
3. Remove sliding pin bolt (lower side).
4. Hang cylinder body with a wire, and remove pads, shims and pad retainers from torque member.
