JK's eat rear brakes, that's just how it is. Make sure your pads move freely in the slides, you may have to sand or grind the metal tabs even on the new pads. Inspect your rotors carefully if they are in good shape you can just do rear pads. I always do rotors with pads for a proper job but at the rate the rears wear I will do them every second time. Hill start assist may contribute but the JK's are heavy, the rear pads are probably too small and they will tend to catch debris and drag. Ah the life of a Jeep.
