Okay, you figure out the spring pressure, vs area of the piston.

I think Wilwood has dumbed down their explanation.

Start by seeing how much weight you need to hang on a return spring in order to get it to stretch to it's installed length. One gallon of maple syrup weighs aboout 9 pounds. But you know the SG to the .01%?

A 1 1/8" piston has .98 sq in, so only 9.8 pounds of pressure at 10 psi. Return springs have lots more 'power' than that- I'd guess 2-3 times.

Plus, how would you maintain any 'balance' in shoe return location with the stepped wheels cylinders on FFPWs?
