Motorized rotary table

I did have a photo after all of the real brake shoes. Here it is showing torque testing of the brake.

Looks like a test setup to see what sort of force (provided by the test spring) was needed. Since you used an air cylinder to provide this force, and I assume air pressure of 90psi (6bar), how large a diameter cylinder did you use to get the brake lock force you wanted?
