MrRidden,
I changed all my lines for staineless on my 1980 R65 (after blowing by a truck with the brake lever to the handlebar) and added a second ATE caliper, changed the front rotors for EBC full floating from
www.cyclebrakes.com and changed the 12mm round resevoir for a 15mm round. I am running Galifer Kevlar (Black) pads.
The EBC part numbers for the flaoting rotors were MD606LS and MD606RS.
The Galifer part number FD013-61532 Kevlar.
The pads are for the Brembo Caliper. I moded them to work in the ATEs.
I still have the stock splitter as I wanted the brake light switch. Stops real good, no fade, when dry. Squeegees abit when wet.
This should point you in the right direction for the years 1979-1984. In 1985 BMW went to the long frame R65 monoshock and I think the front forks with the Brembos are similare to if not the same as the K75. (At the time, I was actually contemplating putting a K75 front end on my R65)
TTFN,
