I am starting a mix and match project between different brake master cylinders and calipers. While this is common on motorcycles I can't find much info on doing it with bicycles. No one seems to list dimensions for their brake systems so I am gonna start a data base.

Here is a good lesson on what matters in a radial master cylinder.

In the caliper is the diameter of the pistons and how many there are.

With both those peices of info we can make informed desicions on what M/C will work with which caliper no mater who makes it.

Any help is appreciated
