master cyl. bleeding

Put it in a vise, preferrably outside, fill with fluid, stick a screwdriver in it and push. As far as it will push, 6 times, or until you stop seeing bubbles inside the mc, with refills, and that's it.

Another trick is after the whole thing is together, is to press the pedal, and crack the lines going to the MC. Always seem to have the last bubble there.
