Does anyone know what the thread is on euro (like birel ) master cylinders and calipers. 1/8 male pipe threads in, so I am guessing it is M10 x1.0. My thought is to get a 1/8 tap, retap the MC and calipers, and then go to -3 AN brake lines, which seem to be quite easily available. I’m just a little worried road racing with old brake lines.
What does one use for thread sealant on brake lines?
