Problem with rear drum brakes

Going back to post #1, as to the shoes coming out at an angle. that would be normal.The shoe moves in an arc, pivoting on the adjuster.
Consider that during use,with the drum installed; the shoes only move out a very little amount. And in the forward direction, the rear one moves hardly at all.
When you apply the brakes moving forward; the pistons move out, the spinning drum grabs the front shoe and jams the rear shoe,thru the star-adjuster,back onto the anchor, and then the braking begins.All the force goes into that pin. When moving in reverse everything happens in the other direction, but the force still ends up in the pin. And from there,yada,yada....lol
