Syringe Bleeding a Master Cylinder

Sign in
Duration:   5:29   mins

In the past, bench bleeding a master cylinder was often a slow and sometimes messy process that often left you unsure if you actually purged all the air out. The process has become vastly faster and easier with the advent of syringe bleeding. Mark Simpson demonstrates how to syringe bleed a master cylinder using a kit from Master Power Brakes and high-quality DOT3 brake fluid.

    Not fully explained. The brake lines sitting aside will not introduce air when hooked up? I went from feeling confident about install to having more questions.

    Why not get 2 short lengths of brake line and attach a check valve (like the ones used to bleed wheel cylinders) and a fitting to fit the master cylinder port. You could then avoid all the plugging and unplugging and the associated mess you get from spilled brake fluid.

      It’s possible that could work, but I always try to keep my brake systems as simple as possible.

      If you try it, send in pics, we’ll gladly share them with fellow members.
