Well I freed up a bit more cable length and took both caliper arms off one more time. I did discover that the housing for the spring with pin is designed to fir in one of three verticallly aligned holes in the frame so that is where my initial spring tension should be focused, I assume top hole is least pressure (am I correct). Please bear with me, I am old and just adjusting from Coaster Brake and single Speed crank technology. Stay tuned for my next installment.
