Today, I received an email from TFS. Among other things, the email contained an image of a brake master cylinder.
Some years ago, there was a discussion on PFF about a slanted MC, much like the one pictured in the TFS email. I checked the TFS web site, and the site shows the same thing. Having just done an article loosely about such things, I went back and referred to the pictures. From the pictures, all brake master cylinders are flat.
Did I miss something?
