No back Brakes!

Wow. Nice looking car. Yes, it looked exactly like yours. The one I have now, has the same top and bottom holes. The holes for the MC lines are angled. Where there is a cap side on yours (my old one) there are just 2 caps like they are plugging the holes.

I know this has turned into a thread with me talking to myself. Checked the brake lines today after 2 days of driving it and sure enough, bottom line is leaking. It is tight. So tight that when I last had the wrench on it, the block was moving and pulling on the firewall. It is tight. I just don't know what to do. Now, the line that is on there, my father-in-law and I made from new stock. We did reuse the nuts, but the line was brand new. The only thing I can think to do is to replace the whole line with new nuts and tube.. I just don't know.

It could be that you tightened the nut so much that it cracked or deformed the flare on the line.

Wait a minute ....

We did reuse the nuts, but the line was brand new.

You re-used the old nuts? That would mean you flared the tube yourself, right? Hmmmm ......

Why does that make me wanna think there might be a problem with the flaring and/or tube size?

There is hand bendable brake line available at part stores that is cheap and easy, that have the nuts and flares installed already. I replaced my brake lines with those and not a problem arose. I think the line nut was 6mm, but not sure

That is what I am figuring is that there might be something odd with the sizing of the flare. However, between my Father-In-Law and myself, we have done many brake lines with the same flaring tool and it has always worked before. Yes, I am to the point of going and purchasing a completely new line from the store and putting it on. However, does anyone know the approximate length of the drivers side front line? I think they sell them straight and I have to bend it. I chose to reuse the old fitting since it came out of the new proportional valve so I know it seated well. Just keeps proving my point of using brand new pieces when I should..

Heres why I had to replace my brake lines..... :mrgreen:

Replaced that Front Left brake line with a brand new line from the Auto Parts Store. Bend here, bend there. NO LEAKS!!! YEA! You cannot imagine how ecstatic I am

I used the master cylinder gauge when I installed my replacement master cylinder. It said in the shop manual that the push rod setting was critical. I bought a bunch of cheap Festiva Rotunda kits on the bay. That gauge was in one of them. I should get into the tool rental business.

At this point, I so far have not had any problem with the replacement MC and any critical settings. Just bolted it together and it so far is working well.
