Title: Blew out a brake line! Help!
Post by: f85gtron on September 07, 2015, 10:34:34 am
During my ac install, i must have disturbed a brake line. Are you guys buying whole brake lines or just repairing them?  Where to get the whole line?

You said you removed or loosened the booster.  Is that where the problem is?  I'm guessing you bent a metal line from the  MC?  It would be easiest to just cut the line at the break, get a union with compression fittings and make the repair up front.  Pulling new metal lines all the way through is a major task.  And expense, if The Fiero Store sells them.

If you have a set of dial calipers, you might want to mic the diameter of the lines.  I found that the clutch line was metric after repairing one with a US standard fitting and it leaked.

There are those who say that you should never use a compression fitting on a brake line, due to the bad stuff that can happen if it fails.
Depending upon which line it is, I might be inclined to find one from a parts car. If nothing else, I'm guessing the Fiero Factory has tons of them, if they'll sell them. (They may not, for liability reasons.)
The Fiero Store will have new ones, but don't they have to be bent to shape?

I have some experience here relining a camper once and a vw beetle and have an old tubing bender I couldn't quite throw away, so I might just repair sections, using double flared unions. That will work better than compression unions. Next, figure out line sizes.

Steve's probably right about compression fittings.  The flared connections would be much better.  I've used compression fittings in the long lost past without problems, but I can see how they could be a safety hazard.

...

Maybe. Doesn't mean I wouldn't try it, in a pinch, if I trusted my abilities, sufficiently. But I don't.

I'm slowly getting it figured out, thanks to this thread on another site http://www.fiero.nl/forum/Forum2/HTML/107264.html (http://www.fiero.nl/forum/Forum2/HTML/107264.html)
There's a little bit of back and forth, but the basics are these:
From the distribution block to the brakes are EUROPEAN BUBBLE FLARE. This is important because the fittings will be correct.
The fronts and back (from the back distribution block) are 3/16 (4.7mm) European bubble flare
The big line from the front distribution block to the back distribution block is 1/4 (6mm) European bubble flare.
If you buy the sections from AutoZone, make sure to read the tag carefully like this:
PAE-xxx. (E=European, last two "xx"=length)
These are made from the new stuff that doesn't rust and is easy to form.
The master uses American fittings and are different.
I'll update with lengths as soon as I find out.

Is this still holding?

Yes, but looks better than factory lines, so now I'll have to do them all, i guess.

Pic?  I'm curious how they compare to mine, since I replaced mine.
