brake line fittings?

[jeremy5780]

I know a few of you guys have switched out your proportioning valves so I have a question. I have 3/16 hard line for my rear brakes. My new proportioning valve has a 9/16-18 female 1/4 tube fitting coming off of it. Well my brake line is 3/16 so it's not going to fit the proportioning valve. I have been looking for a reduce to go from 9/16-18 male for 1/4 tube to any size 3/16 tube and there is NOTHING! what did you guys do?

I am pretty sure the adapter you are looking for is pretty standard. You might try a brake shop for what you are looking for. When I purchased a Crown replacement prop valve that adapter came with it.

I got mine from Oreillys, they were in the back with other "fittings" and no one had any idea what they were or that they were even there. And of course absolutely nothing was in the drawer it was supposed to be in. look back where they keep the pre made hard brake lines.

Don't think for a minute that this is a standard thread for anything but a brake line. finding brake line adapters for the brake light pressure switch was very possibly the most frustrating thing I have had to do on my Jeep. This was kind of free style but I was not able to double flair brake line yet so I had to get a little creative.

ended up looking like this.
I do wish you the best of luck.

Well I went to the auto parts store and had to make this mess up. I really didn't want to do it like this but I really have no other choice. I had to use two adapters to get the 1/4 outlet down to a 3/16 line. They all fit nice and snug I just hope there is no leaks!

Hi Dave , many thanks for the info, but are there any adaptors out there that i could use so not to have to re flare the pipe? if not could you recommend a correct flaring tool for the CJ7 fittings?

That adapter looks pretty good. The flaring tool I use is this one:

Eastwood Pro Brake Tubing Flaring Tool with 45 and 37 Degree Die Set

It is expensive, but it makes factory perfect flares in just about any kind of tubing. The only drawback is that it difficult to use on the vehicle, it really needs to be held in a vise.
