I just had to spend some good hours working on the e brake due to the lever that pushes the shoes being stuck inside the wheel hub. So I am getting ready to leave to work, back up the jeep from the garage and feel the back wheels are dragging. Previous day I pulled the e brake while the jeep was parked outside for a wash. Luckily, the shoes got a bit unstucked and I could use the vehicle. Went to Napa to get a new pair of e brake shoe assembly and went to change them. After replacing them, I noticed that every time I pulled the e brake, the wheels dragged. So I take everything apart again and notice that the lever on which the e brake cable attaches on the back of the wheel hub is stuck. In fact there are 2 levers, interconnected by some sort of hinge, and those 2 parts were actually stuck due corrosion. In the pic, the red area marks the lever the e brake cable attaches to, and the blue is the interconnected lever that pushes the shoes to the inside of the rotor. The pic is taken on the old shoes assembly , which had the actual shoes detached, they just fell out.

Just want to give you guys a bit of warning, this caused me a lot of inconsistent mileage, between 20-30mpg, this I suspect dependent on how often I used the e brake. I recommend to use white Grease on them every year, especially if living within the snow belt. I'll report back with new mileage, now the wheels spin smoothly when e brake is not on.
