Brake lines
I need new brake lines for the front of my xj. Looking into getting these: http://store.4wheelingplus.com/prodd...asp?prod=89702. Anybody use these. Should I also do the rear line?

If you decide to install them, you need to be aware of a few things:
When you install them, you must make SURE that they can't kink, twist, or stretch under any combination of wheel droop, bump, or (for the front wheels) steer.
The stainless-steel outer braid will cut through anything against which it rubs, so you have to make sure that the lines don't rub back and forth over anything important.
Stainless steel lines have been known to fail when dirt gets between the outer braid and the Teflon lining... As the braid moves back and forth, the dirt abrades the Teflon and can make it rupture. If you look at stainless-steel lines on motorcycles, you'll see that many of them are encased in plastic tubing, apparently in an effort to eliminate this problem. The tubing also helps considerably with the abrasion issue mentioned above.
Just my .02.
