The question has been asked about using the original master cylinders found in the 14-13 series with Cleveland brakes.
Well, they will work, with limits. They won't hold for a full power runup....mag check will be ok. The pedal pressure will be high if you really need brakes. On the positive side....you'll never be able to nose over........
I lived this way for 20 years.
You don't need to change the axle for the 1 1/2" ID. bearings. I just made two steel press to fit bushings for the bearings to ride on the original axles. Been that way on my 14-13, for a long time.
I plan to be at Columbia...in my "mystery ship."
