Gir8990 Posted September 13, 2020 Share Posted September 13, 2020 Hey gang me and another me ever are having brake issues with brake proportioning valve. My case last owner took the rear sensing valve out and brake line and replaced the proportioning valve what looked like a xj one. It held pressure but I had no rear brakes at all. So I ordered up a new one and installed it and new fittings and 3/16 brake lines and the darn thing weeps around the fitting under pressure. I got another valve from Morris 4x4 under warranty. Any help or tips would be wonderful. Thankyou. Link to comment Share on other sites More sharing options...
Pete M Posted September 13, 2020 Share Posted September 13, 2020 by no rear brakes do you mean you are unable to bleed anything out of the rear lines? Link to comment Share on other sites More sharing options...
Gir8990 Posted September 13, 2020 Author Share Posted September 13, 2020 Fluid goes back there. But it always leaks at the fitting where the rear brake line meets the proportioning valve. I’ve replaced lines and fitting reflaired it twice same thing weeps and then I lose brakes. Link to comment Share on other sites More sharing options...

ghetdjc320 Posted September 13, 2020 Share Posted September 13, 2020 Are you using steel line or copper nickel? Are you using one of those bar and clamp style flaring tools or a die style? Link to comment Share on other sites More sharing options...
Gir8990 Posted September 13, 2020 Author Share Posted September 13, 2020 Steel line. And. We used a bar and clamp style tool like you would get at a auto parts store Link to comment Share on other sites More sharing options...

Expand Yes, that is an XJ (or ZJ) proportioning valve. If it's weeping around where one of the fitting goes into the valve body, you have a bad flare, not a bad valve.

Gir8990 Posted September 14, 2020 Author Share Posted September 14, 2020 Well it’s leaking from the port that goes to the rear brake line. But I’m guessing it’s the same answer. Link to comment Share on other sites More sharing options...
