View Full Version : Talk to me about flaring brake lines. I'm running a 4 port master on my car and need to buy and run extra brake lines. Ideally I could buy some long lengths bend them to fit, cut and flare the end where needed but I have always heard of the horrors of flaring your own brake lines. What do I need to know in order to have perfectly sealing fittings every time? Also can you run a standard M10x1.

Posted on Fri, Mar 30, PM. Thread identification means learning the thread size and pitch. The thread size is determined by the outside diameter of the male thread, or the inside diameter of the female thread. Pitch refers to the distance from one thread groove to the next measured from crest to crest. There are two systems for measuring threads — metric and imperial same as SAE or American. Metric thread is measured in millimeters.
