With the rudder pedals bolted to the weldments, I could bolt the 4 brake master cylinders to each rudder pedal. I placed the 2 nylon blocks over the ends of the weldment to hold them in position and clamped the assembly to my workbench. I used small blocks of wood and shims to hold a 4 rudder pedals in alignment with each other. I put together the neccessary hardware and bolted the upper ends of each master cylinder to the weldment tabs as shown in DWG 37. With the rudder pedals aligned I placed the lower end of each master cylinder next to the brake side plate and marked the location of the 3/16" hole I would have to drill. I removed the rudder pedals and drilled the 4 holes. After deburring, I reassembled the pedals and bolted the master cylinders to the brake side plates. I set the assembly aside for later installation.
