My car had a total brake overhaul. New lines, master cylinder, wheel cylinders, etc. Now there are leaks from nearly all the joints. I tightened the nuts as much as I can. I really don't want to go further then strip the thread. Not sure what is the problem, maybe the brake place who made the lines for me made them to the wrong tapper angle(?). I was told that locktight will not work with brake fluid, is this true? Is there some kind of a sealant I can use to seal the threads?
Cheers

If the unions, blocks and brake componemts that the pipes are going into have good seats in them, and the brake line is made with the correct angle and a return or double flare, then it is unusual to get a leak.

I have made quite a number of complete brake line setups myself and after finishing a whole car with about 9 lines which will have about 18 ends, I have had one or two weeping when tested, but I have never had to remake an end.

If they are all leaking something is not right. Do not use sealant. The flare should seal 100% if it is right.

Ok, so what do I do now?

[b[... Brake lines are a mechanical fit...
Metal to metal as Helbus said... the fittings have to be compatible 100% and they will seal OK...
If someone made them for You & they don't seal 100% they are at fault....
Its also one of the most dangerous parts on a car... as you know. a leaking brake system can kill You....
Tell the Brake company that did them....
Not just anyone can make a brake hose.... they have to be qualified....
If they don't fix them , contact consumer affairs.....

Compatible brake lines never leak.... usually....
the angle of the fittings has to be 100% correct....

Something is wrong....

I have done My Beetle and no hoses or lines or master cylinder leaked.... Once they are done up tight...
they shouldn't leak...

and loctite cannot be used legally... it wouldn't work anyway
as the metal to metal contact seals these fittings, NOT the thread...

Let Us know how You got on...

Thanks Lee, they were done by Brake Plus. They reconditioned the wheel cylinders too. Problem is I have them on the car now, too late. In the tunnel, etc. Near impossible to pull them out now.

Anyway of fixing them on the car?

Ayyy carumba! Sounds like a real difficult deal.

Ring them up and ask them what they are gonna do to help you out. If they know what they are doing and they did the lins as well as the cylinders, they they have no reason to put incorrect flares on. If they are incorrect, they you are entitled to have them remade. If you fitted them, then you have to take them out. If you can drive it there, then you can sho them and get them to fix them.

Raf, I asked a brake place near me about flaring a line while it's still in my car and they said its possible. I had a peep at the machine that does it and its not exactly a hand-held tool... so I don't know how it can be done, but, apparently, it can... I can give you thier number if you like.

eerk, I hope my new lines dont leak either - the flares look eactly the same as the old ones when I compared them though..

You gotta tighten them up REAL tight WITH A BRAKE LINE SPANNER not a normal open-ender
