Thanks
I saw a R80 1988 with dual lines and a long hollow bolt in another forum. On my R65 the upper brake line is positioned where my new speedo will be and the splitter and small brake pipe use a lot of space. Do you know if the different R45-R100 has identical threads on the master cylinder and caliper? I have ATE calipers, will that be a problem? In one catalog I found the treads marked with M10*1,0 (Brembo). I guess I have to keep looking for a solution.
