Just finished up the brake pedal assembly for the A I am working on, not as fancy as some of the ones you guys have built but it works well for me. It was built so that everything will disassemble easily for maintenance. The main body is made from 1/4" plate, the pivot rod is 3/8" and the actual arm/lever is a GM steering arm. I still need to work in a return spring and a stop but I will probably mount everything before that. I'm glad to be moving on this car again, the past year or so has been crazy for me and I haven't had much of a chance to get back on it.
