has anyone replaced a bad section of brake line with compression fittings? is it safe/legal in Michigan. I have done a little research on the matter, and have seen a few people say that as long as you get good steel compression fittings, not the brass, or stainless steel ones you should be ok. anyone have any experience on using them, or any thoughts?
 
I would veto that idea.

What kinda car? Can you just cut the old line, leave it in, then run a new line the entire distance? Thats how I have fixed them in the past. Measure it out, buy full length lines and couplers, make sure you have the right fittings and yojr back on the road.

If you were closer to livonia Id tell you just run it up to my shop.

As stated correct way is to replace or section the line with flared fittings. If that is not possible or feasible you can get hydraulic tube fittings that are rated to 3000+ psi. These will come in steel and stainless steel only. Every industry uses them and installed correctly will be perfectly safe. Just takes alot more torque to correctly compress a steel/stainless ferule vs a brass one. If you go this route check a local Parker Hydraulic store, McMaster.com or similar industrial supply not your auto parts store.
 
Straight pre-double flared/bubble flare lines containing male end fittings in various lengths are able to be purchased at your local parts store. Bend to fit the line in replacement of old line while using an union fitting to couple together the flared ends with aforementioned fittings.

Be sure to keep the male fittings ahead of your bends at all times. Use something such as masking/painters tape as a slide stopper. Brake lines are relativity easy to manipulate by hand to recreate the bends desired. Fuel lines tend to be less forgiving.

If the lines contain a lot of corrosion, consider a full new line. If you're working with proportioning valving or an ABS system, the likelihood of those components falling victim to being exposed to foreign debris is very high.
 
Ive seen them used before but I would never do it, one good panic stop and I bet they'd be gonzo. It's not that hard to do the right way, why take the chance?
 
I had to replace the rear brake line on my 4th gen once. I just bought a couple four foot sections with fittings from Napa and ripped the old one out. I got the length to within about six inches.

big NO NO. I worked at a "brake shop" for a little over 8 years and I was the "brake line bitch"... lol. If you get the chance, try out that copper nickel brake line, that stuff is "the shit" to work with!

I just bought a bunch of that copper stuff to make the brake lines for my Chevelle. I fooled around with it a bit and it is pretty easy to manipulate around and create the double flares with. I bought rolls of it and I don't know if they make pre-formed pieces of it yet...

grr

I did see they had pre cut lengths that were already flared at the napa warehouse the other day.
 
Chances are you will repair one section and then another will pop Id replace it. I used a compression fitting on a van I bought that I picked up super cheap guy said it had to be trailered home drove it 2 hours then replaced it before I sold it.
