Bleeding Master cylinder

What's the procedure for bleeding the master when it's on the car?

It is basically the same as bench bleeding. Run a tube from the line connection fittings back into the master cylinder. Then press pedal down smoothly and release, repeat this until there are no air bubbles coming from the tubes. Do not pump the pedal just press down smoothly and release. Oh yeah, fill master cyclinder first, haha. Good luck, it is easy and only takes a couple of minutes.

Same as if on bench.:-D If you installing new MC, It`s easier on a bench, chucked in vise. If it is an existing MC and you feel their`s air in it, :dontknow: and you want to start from square one. procedure is plug each port on MC, and slowly pump pedal until all bubbles disapear. kinda hard to see while sitting in car. Thats why its best on bench, or if you have a helper. these plugs come with brake bleeding kits or provided with new MC`s. some have tubes that just loop back into resevoir. Then you have to bleed all lines again. fun,fun.
