how to bleed master cylinder

[Blake Carstensen]

hey guys, i did a search and nothing came up for me. but i changed my vacume booster the other day, and i took my MC right out to clean it up. painted it and what not(see how long that lasts) anyways, i want to know what needs to be done to bleed this now?

i remmeber reading about bench bleeding it but didn't stumble upon that in my searches. if mounted on the car, would i undo the brake lines at the MC to get the brake fluid started? i take it, there is air in there, and by hitting the brake pedel, its not pushing anything

cheers

Bench bleeding: You need to hook a fitting to each port on the MC and run a rubber hose from them into each side of the reservoir, make sure they are submerged in fluid then cycle the plunger several times to remove all air.....

Make sure the cylinder is level when bleeding, otherwise you will get air pockets and spongy brakes.
