I have a 1929 Mercedes Gazelle replica with a 1980 Pinto drive train (including the brake set up). The brakes are manual, F-disc, R-drum. They work great except I have to push the pedal a long way. I was wondering a few things.
1) Did the Pinto have manual brakes? There is no room for a booster in the Gazelle.
2) How much pedal travel does the Pinto have?
3) I am thinking about adding residual pressure valves in the hopes of shortening the pedal travel. Does anyone know if this will work?

Thanks for the help.

Thanks Art.
