Bench Bleed Master Cylinder

[Tyron68]

I’m gonna ask what is probably a dumb question. I’ve got all my brake lines installed/connected and now I’m down to bench bleeding my MC and connecting the lines to it. If the master cylinder has brake fluid in after you bench bleed it, how do you connect the remaining lines to the MC without fluid coming out of the ports? My MC is a Raybestsos (MC36283). It came with these three little plus that I am assuming are what I use to bleed it. Seems like when I take those out to put the actual lines in the fluid will just come out of the MC? It’s a front disc/rear drum 69 charger.

You might get one drop.
It will be fine

It could certainly be more than a drop. Put something under the to catch any fluid. Everything looks so clean on your car don't damage it.

Are the lines on the wrong side?

Actually, what's left in the tubes you used to bleed the m/c will all drip out - that can make a mess. But you shouldn't get much coming out of the m/c in the short time it takes to hook up the main lines.

Roger that. Got all ready to bench bleeder my MC today and the kit didn’t have the correct size bleeder plugs. I’m gonna put a bunch of towels down inside the engine bay to make sure it doesn’t drip on anything when I’m putting it on.

I've found the best way to bleed brakes on almost any vehicle including my B body is vacuum bleeding at the wheel cylinders.
Right rear first, LR, then RF and then LF.

I did this twice a couple months ago, one a single bowl master bled on the bench and on a 2 bowl carb bled in place on the car. Surprisingly, I don’t think I lost a single drop of fluid on either one installing and hooking up lines. But I did put newspapers and a couple paper towels under them just in case.
