      MAth question please

      I keep hearing that the rear piston should be 40 -60% smaller than the front piston. Is this correct?
      So taking my 2.8" front piston 3.14x2.8= 8.792

      So for 50% of 8.792 would obviously be 4.396 Then to find the Diameter of that would be 4.396/3.14= 1.4"
      Correct so far? It dont seem right. 1.4 is 1/2 the dia. but in my mind that cant be 1/2 the area...

      Help Im mathmaticly retarded.

      Nothing says "I built this" better than tool marks and dykem blue..
