The PowerStop K3167-36 is a front-axle Z36 Truck & Tow kit that pairs a Z36 carbon-fiber ceramic brake pad with a drilled and slotted rotor for the 2010-2018 Ford Expedition. The manufacturer frames its Z36 line as uprated hardware that improves heat dissipation and stopping power without sacrificing ride quality, which suits owners who tow trailers, haul loads, or run larger tires. For Expedition owners who want more fade resistance on mountain grades, this kit targets the front axle, where most braking load sits during towing.
Owners on user forums say cheap drilled rotors crack very easily since they are just junk rotors with holes drilled in them, which makes a matched, engineered rotor-and-pad set a safer buy than budget parts. One 2019 Expedition owner on a user forum reported that a PowerStop front Z36 setup made a huge difference in bite, pedal feel, and fade especially having to smash the brakes after a couple hours of summer interstate driving. Because this is a front-only kit, the rear axle keeps its stock pads and rotors unless you buy a separate rear set.
No. The manufacturer's part designation for K3167-36 is front-only, so the rear axle needs its own pads and rotors.
Yes. The manufacturer's install guidance covers bleeding the brakes and following a break-in procedure after the new parts are installed. Owners on user forums note that ceramic pads take some extra care during the break-in period.
Owners on user forums report stuck rotors on this platform, and one noted that the PowerStop rotors include two threaded holes that can be used to push the rotor off the hub. Cleaning the hub face and applying a thin coat of anti-seize at the contact points is a common step to prevent this next time.
Owners on user forums describe the front swap as a manageable job for a home mechanic with a breaker bar, a torque wrench, and a jack setup rated for the truck. Plan for a seized rotor or a stubborn bracket bolt, and check the torque specs for the caliper bracket and slide pins before reassembly, since owners say the service procedure calls for replacing certain bolts. Wire-brush the rust off the hub and rotor mating surfaces, then follow the manufacturer's bleeding and break-in steps to get the best stopping performance from the new pads and rotors.
