So I was disconnecting my battery today, and for some reason disconnected the positive first and happened to nick one of the brake lines causing the line to have a slow leak... :/

What's the best source of action to fix this? I'm stuck as to what to do, I don't think it's going to be easy finding a replacement brake line.. Would I be best to cut the broken part out and put a new piece in and some compression fittings in?

There's another join further back in another line that I didn't even notice till today either... not touching that for now anyway.

So annoyed with myself :s

Kunifer brake line - you can make a new pipe.

You'll need to bleed the brakes afterwards

Hmm..

I'm yet to get in contact with my wrecker, it's a huge line. Should I replace the whole thing?

Also do you have any idea what size it is? If I'm going to replace the whole thing I'll either grab a piece that's already done off another 80 or just get it local. The problem is nobody has a bending tool?

Anyway just for reference.



Left is roughly where I broke it, and right circle is the line that it is.

For the life of me I cannot undo the connection, it's bolted in so tightly.. It just rounds off the bolt :s

3/16" is standard size. Can't tell where it goes in the pic but it's good practice to replace the complete line

Yeah, I'm thinking that too.. Will probably have to go without a car for a week or more since that's the case, but at least by then I'll have a little bit of cash to play around with.

It appears to go to the front right wheel. Hopefully not too hard to replace.. My best bet is getting one off another Audi 80/100. Hmm

I've replaced sections before, using male and female unions and never had an issue. Trying to get round the back of the block is more trouble than it's worth replacing the whole line.
If you haven't got a vice mounted flaring tool, get down to your local garage to flare the pipe. The hand flaring tools are next to useless.
To get the union out of the ABS block, you'll be best cutting the line close to the fitting and getting a socket over it.

I did the RH front on mine and it was a awkard fecker replacing it all but doable with patience. I got one of these cheap and cheerful tools for bending which worked great in tight spaces.

Hmm, well for now I've put two compression fittings in... I can get a stainless line for basically free so I'm thinking I'll just do that anyway? I'll have a test fit with bending it around a thick pipe and sitting it above for a test fit. Otherwise I may just end up pulling the slack back and making it fit..

I'll get a photo of my temporary fix later today.. It's not so bad either, we re-traced it two-three more times and found it to be connected to the overflow/fill section.

I will either be replacing the whole line soon, or flaring it and fixing it correctly. I may be able to grab another already bent line off another Audi 80 as I've mentioned..

I've got to add that I've found some flares/joins already in my system as well while trying to trace them so I feel more confident with having flared brake lines.

Also I'd like to ask what is the usual technique to bleed the brake system of air with an ABS system? Smile

Thanks for all the help so far guys! Smile
