Brake reservoir cap question....

So I made myself a power bleeder using parts from home depot and couldn't get myself to cough up $17 for a cap at the dealer because no one else carries it. I used the original cap and made a fitting on there that I plan to leave permanent. It is made of brass and is capped off from outside air. Is this ok?

Haha, guessing this is exactly what I was talking about in the other thread? Using it to pressurize the brake system for bleeding.

I dont see anything wrong with it if it has a good seal. Well, except it probably looks ugly :P

If you look at the cap on this site

http://faculty.ccp.edu/faculty/dreed...eder/index.htm

It's the same as his cap except I inversed the brass pieces so that it'll have the long pointy thing aimed downwards and keep the reservoir a little lower if otherwise. Also theres the thread for the cap when not in use.

All the pieces can be found at home depot to modify it the way you like or to fit pieces you already have. I'm not sure if brass is ok for brake fluid though they do have plastic pieces as well. Good thing is we're no using silicone or glue.

Just FYI, your cap MUST still have a vent in it so the MC can pull fluid through the reservoir, the system is not 100% sealed its not suppose to be. Other than that it doesnt' really matter if you keep your DIY bleeder in there.

Isn't the vent hole on just one side of the rubber diaphragm? So if you made the bleeder in a way to pressurize only the outer side of the diaphragm then it should great.

The cap itself doesn't have a vent hole. Underneath the cap is a black rubber thing with a white plastic thingy. The rubber piece actually has two layers with a slit on both the top and bottom with the white plastic piece acting as a plunger of some sort it seems, opening and closing the vents as needed? Not too sure... Should I drill a very small pin hole behind the rubber piece? That way I assume as I pressurize it the rubber peice would go up and block that pin hole and alls well? And when not pressuring it'll vent in as normal? Can condensation occur through this method?

I just used my Diy power bleeder but I can't seem to get a good seal on it... Fluid was leaking from the underside of the cap... As well as the connections... Anyone with tips on how they made it sealed tight with out the use of sealants?
