Proportioning valve hook up
 
3 Attachment(s)
I have a brake kit from Inline Tube. The proportioning valve inlet for the rear doesn't match the line from the rear. Proportioning valve rear inlet is 1/2"x18 and the rear brake line is 3/8"x24 I believe. I would think they would make sure everything fits before they sell it. :rolleyes: I rummaged around my spare parts and found something that "May Work" I'm no mechanic and I would like to get as many opinions as I can before I proceed. We all know how important good brakes are. Hopefully the pictures will tell the story. Somehow it just doesn't look right. Is it proper to have a brass to brass coupling ??? Thanks, Jack

Call them for the fix - you bought a system. They supported me an a couple of their parts screw ups on my car.

Yes it is. As long as the flares match. The important thing is to have the flare angles correct so they seal on the flare area. Not the threads of the fitting. Many assemblies use brass to brass fittings.

Adapter fittings for inverted flare connections are readily available, but the one in your pictures is not the correct one for this application. Note how small the tapered area is on the nose of that fitting. It won't seal on the flare in the prop valve. You need a Weatherhead WH7909 adapter fitting. NAPA should be able to find one for you. These are called "dual master cylinder adapters" by some suppliers. Here's another source:

Thanks guy's That's just the answer I was looking for. I didn't think it was right. There was very little surface bearing. It just didn't feel right. Thanks again !!! :thumbup: Jack

I just got some brake adapter fittings from carquest, they carried Edelmann. You can look up online what you need and go in with the part number. I'm not sure what you have for stores in your area.

I looked around town today, but no luck. One place told me to run a drill bit down a smidge, 45 degree. I won't be trying that. :rolleyes: I have a Weatherhead WH7909 adapter fitting ordered and it should be here tomorrow. Jack
