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 bleed 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.
