I have a 2013 JKU with AEV 2.5" lift. I'm doing research on the parking/emergency brake functionality. Mine doesn't hold and it's been to the dealer 4-5 times over the past 6 months. Everything has been replaced, Cable (twice), handle and assembly in the center console and all components at the rear wheels. I took the rotor off and tested that the Handel has to be pulled up 3/4 of the way before the shoes start to expend. I have adjusted the star bit to where I get a little bit of resistance when rotating the rear wheels. Anyone have similar issues?
