broken brake line.
footman:
So I'm not too sure what the guy from Falveys was talking about $240? I removed the broken line and took it down to Valenti, $8. Of course the right side was quite a bit more but I figured they all come pre bent so I ordered both fronts and the rear. They'll come in tomorrow.
So on to my next question: Tips on bleeding brakes? Can I fill the reservoir and pump the pedal till I see fluid from the line then attach it to the flex hose?

Take a plastic soda bottle (20 ounce minimum) and clean it and dry it real good. put a hole in the cap that will allow a fairly small clear rubber tube (one that would be tight on the bleeder nipple) to fit through. Add a couple ounces of brake fluid to the bottle, replace the cap and ensure the tube is IN the fluid. Attach the other end of the tube to the "bleeder nipple" on your caliper and have someone push your brake pedal slowly and all the way to the floor. If there is air in your brake line, you should see bubbles being blown into the fluid in the bottle. If after a few pumps, the bubbles cease to appear, the air is out of your line. Tighten the nipple(before removing the tube from the fluid) and you should be good provided there is no more air in the rest of your lines. Generally, you start from the tire farthest away from the Master Cylinder and do each tire getting closer as you go. Hard to think that air would have migrated that far back but I suppose its possible. If you have a crappy pedal feel after doing this, then you most likely have to start at the back and do the whole system. Just FYI: DO NOT add the extra fluid from the bottle back into your master cylinder. That would be bad.
Clear as mud?? ;D

Bleeding the brakes isn't hard, but it can be time consuming. I snapped the main hardline going to my rear axle on my XJ this past winter when an idiot came flying out of a driveway behind a snowbank. I hit the brakes hard and then I felt a pop and the pedal went to the floor. I got it home and replaced the entire line from the master cylinder with just tubing and flaring some ends I bought. A long time ago I picked up a brake line bleeding kit that sucks the fluid from the wheel rather than pushing from the pedal. They are cheap and I've found that they work pretty good, especially when you're working by yourself. Just make sure you refill the brake fluid between each wheel. You don't want it to run dry and then push or suck more air into the lines.

Thanks all for the much needed info. I do have one of those miteyvacs that I've used for my motorcycle. Bleeding brakes on a bike just seems alot simpler but I was reluctant my first time on that too.
footman:
ok so I fixed and bled the broken front left line and just like Reg said "pop" goes the rear line. OK no biggie bc I ordered the new one. So heres my question, how do I bleed the rear with the line t'ing off? Do I just pick one wheel and go with it?
