Bench Bleeding Master Cylinder

NOTE: Bleed tubes must have a residual pressure check valve installed to keep tubes from siphoning brake fluid.
  1. Clamp master cylinder in vise by mounting flange. Install and tighten threaded end of bleed tubes in outlet ports of master cylinder with opposite end of bleeder tube in reservoirs. Fill reservoirs with clean brake fluid so that bleed tube ends are submerged in brake fluid. See Fig 1 .

  2. 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.
