[QUOTE="Flyer58, post: 426957, member: 18629"] I changed out both the hard brake lines and rubber brake hoses and it made a huge difference in my 92 YJ. The typical problem I had was the rubber hose had collapsed so the front brake didn't fully release and would drag, pulling the Jeep to the right and getting very hot. Two hoses in front and I think one in the rear by the differential. Helpful hint.. I tried for hours to separate the hoses from the hard line and eventually resorted to cutting all the lines since I was replacing them anyhow. I bought a 20ft roll of Poly Armour hard line and shaped them to fit. It will require you to cut and make a double flair end, the auto parts store should have free loaner tool for doing the job. Changing out the lines/hoses gave the brakes a firm positive feel. I also had a frozen brake booster check valve, plastic fitting that connects to the hose and pushes into the brake booster. I was getting no boost prior to that. To test that part of the system just press on the brake pedal with the engine off and start the engine. You should feel the the pedal go further down when the engine starts. [/QUOTE]
