45° double flare, with male threaded tube nuts, they fit in "inverted flare" fittings.
Originally I know it was 1/4" line for most if not all, and if not for everything then there was some 3/16"?? It's been about 11 years since I replaced mine and I went with a different configuration with disc brakes. Perhaps someone else can recall exactly what size line where, if any 3/16 was used.
