I just got off the phone with Dave Krolak, we were discussing the brake seminar. He really is putting together an in-depth session from model 'a' to hydraulic conversion to master cyl sizing and modern disc brakes. He is going to let the discussion go in whatever direction it wants to take and he'll have examples of the diffrerent systems.
Dave used to teach this stuff at Wyotech and now works in his restoration shop in Maryland, so if you want to learn from a master here is your chance.
