2001 TJ Sport, 110k miles.
I have seen a lot of different brake designs in my day, but never anything like this. When I pulled the first one, I thought maybe E-brake issue, or something to that effect. But both looked identical! I looked at replacement rear shoes for 2000 and 2002, and all of the shoes made are normal - full face. I also looked at replacement drums for 2001, no slots.

Anybody ever seen this before?

Yes I have ran across shoes designed that way in the past you can just replace them with regular style shoes & have the drums turned if they are thick enough to turn.

I'm sure there's a reason for the grove or it wouldn't had been engineered that way, but I'm of the opinion that more surface = more stopping power.

I agree. I replaced them with normal shoes and drums. Did the wheel cylinder while I was in there.

Just struck me as very strange. Parts shop was perplexed as well.

This type of design is along the same lines of grooved/slotted rotors, except instead of the drums being grooved/slotted it's the shoe. In reality it probably doesn't work as well as on paper, especially in a rear application that does very little braking in the first place.

never seen them before till we worked on a 2002, just thought that something was stuck at one point. since one side had more groove than the other
