PROPORTIONING BYPASS VALVE

Inspection

1
Connect two pressure gauges [9,810 kPa (100 kg/cm², 1,422 psi)] to the pipes.
05U0PX-030
2
Measure the fluid pressure from the master cylinder and to the rear brake.
05U0PX-031

CAUTION

• If not as specified, replace the valve assembly. • After inspection: Add brake fluid and bleed the air. (Refer to page P-6.) Check the brake lines for fluid leakage.

Replacement

1
Remove in the order shown in the figure.
05U0PX-032
2
Install in the reverse order of removal.
3
After installation: (1) Add brake fluid and bleed the air. (Refer to page P-6.) (2) Check the brake lines for fluid leakage.

CAUTION

• Brake fluid will damage painted surfaces. If it does get on a painted surface, wipe it off immediately.
