Would this help at all?

If someone could help me draw a FBD and figure that out, i've highlighted where the piston pushes and the rotation points

Post these same pics with the horizontal and vertical distances between the cylinder point and pivot points noted.

Also x-y distance to wheel shaft from pivot point
