Was leary about this part, have a 75 cj5, I converted to disc brakes. Had this and the brake lines installed in less than 3 hours. Haven't ran the jeep yet, still in the build but everything worked perfect. Didn't order the bracket, should of, ended building my own!

Leaked after a few weeks

As many have reported, this valve is notorious for leaking out of the metering valve dust cover. After a few weeks of use, over half of the brake fluid from the rear reservoir of the master cylinder had leaked out.

Ordered two of these - they both started leaking fluid after about 3 weeks of use out of the metering valve dust cover.

Two things I wish I had known

The rear port is NOT 9/16-18 thread pitch. It is 7/16-24 so you will need a new fitting and a brake line flaring tool. Second thing- almost certainly your original low pressure sensor is a two prong connector. Pull the cap and check. If so, you will need item 52 which is made by the same company. It's $3.99 and you can just splice it into your existing 2 wire and it will work just fine. My thanks to George Perez for all of the free advice.
