proportioning valve used as a shutoff?

[WSSix]

Crazy idea time. Can I use my proportioning valve as a shutoff valve while I work on my rear brakes? I'm trying to prevent the fluid from coming out of the master since it will be sitting a few days while I do the work.

Which I guess brings me to another question. Do they make plugs and caps that I could screw onto the different fittings in the future while I do brake work?

Thanks

prop valve doesn't completely shut off flow.

Yes, caps and plugs are the best way. I usually disconnect the line between the body and axle. Plug the line at the body with an AN cap. You can get inverted flare plugs too.

Search Amazon or your local auto parts store for brake line plugs. They work great Trey!

Dang! Yeah, I'll work on finding the caps then. I hate dealing with brake fluid.

That was my plan, Vince. I have all new braided lines from Tobin for the rear so the body to axle line has to come off anyway.

Thanks

Good cause that rear inverted flare fitting sucks to put on...especially when brake fluid is pouring out of it and down your arm. -3 AN hose, one hand, not even looking, in the dark.... goes on so easy.

Oh, one thing I use to do at he dealer is use a brake depressor from the alignment machine. Open the line, put a bucket under it, depress the brake pedal, lock it down with the rod and hold it down. As long as there is a vacuum in the line fluid will not drip out.

Replace the line, tighten it, make sure the master is full then release the pedal and bleed like normal. worked for me.

That's a neat trick, Vince. Makes since that it would work, too. Thanks
