Overview
The Power Stop KC3090 is a Z23 Evolution Sport Performance 1-Click brake kit with calipers for the rear of the 2007–2018 Jeep Wrangler (JK).
This kit covers the rear brakes of the JK Wrangler with drilled and slotted rotors, Z23 Evolution Sport carbon fiber infused ceramic pads and calipers. Power Stop says every caliper is remanufactured, lubricated and pressure tested at its Chicago, IL facility.
Slots add pad bite and air circulation, while the drilled holes and slots let debris, dust, gases and water escape. Drilled rotors also reduce rotor weight and give the wheel area a distinct look.
The Wrangler JK ran for twelve model years, and Power Stop lists KC3090 across the whole 2007–2018 span for the rear axle. That makes it simple to match by year. The front brakes need a different kit, and anyone upgrading both ends should plan for two part numbers.

Rear brake maintenance basics
Rear brakes on a Jeep handle a smaller share of stopping force, but they still affect stability under braking. Pads wear faster when drivers use the parking brake often, and a sticking caliper slide can overheat one wheel. Checking slide movement and the parking brake adjustment at each pad change helps the rear wear evenly.
Ceramic pads produce less dust than many semi-metallic options and stay quieter during light use. Ceramic compounds still need heat to work well, so avoid long downhill braking with the pads cold. Inspect the rotor face for hard spots and blue discoloration, which indicate overheating.
- Test the parking brake after each rear service
- Clean and lubricate caliper slide pins with the supplied lubricant
- Check the rear pad thickness at every tire rotation
