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 at mounting flange. Install bleed tubes in outlet ports. See Fig 1. Fill reservoirs with clean brake fluid ensure bleed tubes are below brake fluid level.
- Slowly compress and release piston assemblies until bubbles no longer appear in brake fluid. Remove tubes, and plug master cylinder outlets to keep fluid from draining.
