PowerStop Z17 Rear Brake Pad & Rotor Kit KOE4631 — Ceramic low-dust pads, OE-style milled rotors

If you need a direct, affordable upgrade to worn rear brakes without changing driving habits, this complete kit replaces pads and rotors in one package. PowerStop engineered the Z17 pads for daily driving: ceramic formulation for minimal brake dust, chamfered and slotted faces for smooth engagement, and rotors precision-milled to OE dimensions for stable pedal feel and reduced vibration. The kit includes rubberized shims and stainless-steel hardware to make the swap straightforward and bolt-on ready.

How will these pads and rotors affect everyday braking?

The Z17 ceramic pads prioritize quiet, consistent stops and low dust over aggressive performance. They break in quickly thanks to thermal scorching and slots that help establish pad-rotor contact. Matched with mill-balanced OE replacement rotors, the result is predictable pedal response and minimized noise during typical driving.

• Low-dust ceramic compound keeps wheels cleaner.
• Slotted, chamfered pads reduce initial noise and vibration.
• Precision-milled rotors maintain smooth stopping and consistent wear.
• Thermal scorch process improves early bedding-in performance.

Will installation require any modifications or extra parts?

No modifications are needed—this is a true bolt-on kit that supplies everything necessary for rear brake replacement. PowerStop includes stainless-steel installation hardware and rubberized shims so you won’t need to source separate mounting parts. Typical home-garage tools and a service manual or torque chart for your vehicle are sufficient to complete the job.

• Includes two rear Z17 ceramic pads and two OE-style rear rotors.
