Hi guys, I need to change out my metering valve(combo valve) on my '69. Is it possable to do it without emptying the master cylender?? I do have my inner fender well out, so I'm not too concerned about spilling a little fluid..

I REALLY don't want to get in to removing the master to bench bleed it.

Thanks in advance,
Scott

Scott scott i have a set of rubber plugs that i use to plug up just these types of things. i think i got from snap on many years ago. but they basically consist of about 8 or 9 different plugs on a key chain type holder. i think if you went to an auto parts store you might be able to find. but it sure sounds messy to me. i just replaced my front lines on my lemans and i did not have to re-bench bleed my master. i dont think you would need to either. just remove most of the fluid. and hopefully the rest wont gravity feed out. but like i said my did on my master and no re bench bleeding was neccesary. tommy

If you keep the lid on the master cylinder and it has a good seal, wouldn't the vacuum keep the fluid from running out?

Not enough fluid is going to leak out of the fitting for you to have to worry about it. If you're really concerned, put a plug in. But at most you should get a few drips. Place a rag under the MC. Bench bleeding the master isn't necessary in this case either.

Thank you, thats what I was hopeing to hear.. Now if that valve would show up at my door... Ground Up is sending it out direct from the manufacturer..
