broken brake line.

(1/4) > >>

footman:
Can you guys give any tips on replacing a broken front drivers side brake line?  I plan on calling around for a stock line but I'm sure it just doesnt go in like butter.  I looked in the factory service manual and to my surprise there was nothing.

reg:
It is much cheaper to by the length of tubing you need and the ends.  you can borrow the flare tool for AZ.  WE redid most of my brakes when we built my YJ  :o  pretty easy actually.  depending on how much line you'd need, I might have enough for you, but no ends.

footman:
So I just called a dealer and its 240 for just that section. 
Reg,  If i were to buy a straight peice from AZ how exact does it have to be in length to the stock (do I have to put all the bends that are in it coming out from the portioning valve)?

what you'd buy is the flexiable tubing.  it comes coiled up and you can bend it twice before it is too stiff and will kink.  take a piece of string, lay it along the old line, measure the string add 10 inches, then go buy that much.  iff you have more than one or two lines, it might be cheaper just to buy a 20' roll.  the ends are like .25 a piece or somthing real cheap, just get the right ones.  the DOUBLE FLARE flaring tool is the one you'll need.  best bet is to:
1. measure what you need
2. cut off the end of the broken line with the connection still on it ( this way you know what size of connection and tubing you'll need.
3. tell me where your jeep is so we can get it on the road again  ;D It shouldn't take long.

The hardest part of the whole thing is getting the old lines apart without damaging the porportioning valves (one fwd of the master cylinder, 2nd one on rear axle)

If it is just the flexable line that goes to the wheel cylinder, you'll have to buy them.  I have a few lying around from the yj I think.  I'll look, they might fit.

Axle:
I didn't get to see what part of the line broke yesterday, Stephen.  Could you post a pic of the break?  That would help determine exactly what you need.
