After taking a closer look at two of my rudder / brake pedals I realized that the arm for the master cyl was not perpendicular to the pedal. After some investigation I discoverd that the >063 angle supplied with the passenger brake kit was not 90 degrees, but closer to 85 degrees. This is just a case of some bad material from the manufacturer. Luckily I have pleanty of 3/4 X 3/4 X 0.063 angle, so I remade the parts for those two pedals.
