Brakes Dragging - Pushrod too long?

Follow up -

So it wasn't the pushrod length, I actually made it a little longer once I figured out the problem.

The bolt that goes through the pedal arm and the push rod was causing some binding. When I had it tight enough to not have any slop between the pedal arm and the pushrod, it was too tight and did not allow the pedal to come back up all the way. If I loosened it any, there was a noticeable amount of slop between the pedal and push rod. I grabbed a teflon washer and put it between the joint, tightened the nut back down and all is well again, there is no slop, and the pedal returns all the way. It's not a shoulder bolt like the stock one, it's the bolt that came with the Dr Diff adjustable pushrod.
