A bi-directional back stopping clutch is provided having a hollow outer race, or drum, disposed about a first axis. The outer race includes a radially inner friction surface. The clutch also includes an input member rotatably supported within the outer race and first and second brake shoes disposed within the outer race and in engagement with the input member. Each of the brake shoes includes one or more arcuate surfaces corresponding to the inner surface of the outer race with each arcuate surface defining a slot. The clutch further includes an output pin having a first portion disposed between the first and second brake shoes and a second portion disposed within an opening of an output member. Finally, the inventive clutch includes a hardened insert disposed within each of the slots in the arcuate surfaces of the brakes shoes. The inserts each include a groove formed therein which channels a lubricant within the clutch away from the frictional interface of the insert and the inner surface of the outer race.
