Bench Bleeding Master Cylinder
NOTE:
Bleed tubes must have a residual pressure check valve installed to keep tubes from siphoning brake fluid.
- Clamp master cylinder in vise by mounting flange. Install tubes in outlet ports. Fill reservoirs with clean brake fluid so that bleed tubes are below brake fluid level. See Fig 1 .
- Slowly compress and release piston assemblies until bubbles cease to appear in brake fluid. Remove tubes and plug master cylinder outlets to keep fluid from draining.
