Leaking Brake Line

[reddie73]

I'm having a problem with the hard line going from the brake master cylinder to the proportioning valve on my 71 240Z. The previous owner cut the original lines and I've bought several lines that were already flared and had the end fittings. The length of the lines have been 12 inch aluminum and steel lines that I bent to try and fit. I can't seem to get the line to seal properly. I've tried several times and all eventually seep fluid. I've tried teflon tape on the end fittings ,but they still seep fluid. The you bend lines come in 12, 18 and up inch lengthes. Does anyone have any suggestions that might help?

Which end is seeping?

I suspect that the threads or flare cone in the end that seeps is messed up. Remember that you need to get the 10mm Japanese brake lines. I don't know how many lines I ended up returning because the guy at the counter thought it was something else.

tape, glue, or other stuff will not stop it from leaking. Like Walter said, make sure you have the correct lines that are for an import (Metric) Make sure the threads are good on both the master cylinder and the proportioning valve and there is not some trash or object in the way keeping the flare from seating correctly. Good luck

Does your 71 still have the stock master cylinder with the large reservoir in the front? If it does I have a pair of nice stock lines that go from the master cylinder to the distribution block. The flare nuts on the lines are perfect as are the lines.

I have a new master cylinder from Courtesy Nissan that is the large reservoir in the front. I would be interested in the lines if you want to sell them. Contact me norrisrx7@suddenlink.net.
