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.
