Hi guys just want to let everyone know that jeep has finally fixed the ebrake issue. There is an updated handle and new cables. I installed it today and it works. The new cables are shorter. I got mine on eBay as a package and it said the cables and the handle were needed. I didn't notice anything different with the handle though. Just thought people would like to know. I will also update in a week or so to let everyone know if it still works.
All JK e-brakes work, at first. Use them a dozen times or so, get them dirty/muddy a couple times and they're toast. Shorter cables aren't really a good idea if you actually wheel you're Jeep and flex it out. If short enough, they'll actually inhibit droop.
