I am putting a single Brembro radial mount caliper from a BMW s1000rr onto a vintage BMW, anyone have guesses for good master cylinder size to go with the single caliper set-up?
Have read some reports of decent performance with stock airhead master cylinders in the 14-15mm range, but nothing definitive.
