96 XJ disc brake conversion - Upgrade proportioning valve?

Hey everyone,

I did a disc brake conversion on my XJ a while ago from a 97 ZJ and I grabbed the prop valve. The only issue is that it doesn't mount to the XJ. The black piece that connects to the frame looks like it was punched onto the prop valve and I haven't gotten it off. I'm assuming if I grind that part off with my dremel that it will just slip off and then I'll do the same to the one on my XJ and just mount the new prop valve to the black piece.

Is that the easiest way to do so?

Does swapping the new prop valve make the braking that much better? I did feel like my brakes got better once I did the disc swap. IT seems like it'll be a hassle to swap them... just wondering if it's even worth it.

Also, once I take the prop valve off won't a bunch of brake fluid go everywhere? Will I have to bleed the brakes when I'm done?

Any advice is greatly appreciated.

REmove the guts from your prop valve and replace them with the guts from the ZJ prop valve.

If you own a Renix Jeep, you'll want to check this out.

Especially you guys in the salt belt and/or don't have the flare nut wrenches, swap the guts. Even I did it in Arizona.....

I did that. The valve from the ZJ was black and a little smaller. When I put it in the prop valve leaked fluid from that little hole with the rubber piece from it so I just put the old one back in and figured I'd leave it alone.

Yeah, I don't know why it did that either. Didn't see anything about it on the forum either. The screw caps were different sizes so I couldn't use the one from the zj. I noticed my brake light went on after... Does it go on if you have air in the lines or something?

Oh well. I remember having significantly better braking when I did the conversion though so overall I'm still happy I did it.
