The Power Stop 17-976B is a front Z17 Evolution ceramic pad set, and the manufacturer builds it on its Z17 Evolution Plus formulation. The manufacturer describes it as a ceramic compound meant to deliver stopping power while cutting brake dust and noise. Construction details include OE-style positive mold technology, a thermal scorched friction surface for a quicker bed-in, chamfered and slotted pads, and a powder-coated backing plate for rust resistance. The manufacturer positions it as a stock-replacement daily-driver pad for a clean-wheel, quiet-stop upgrade on a 4Runner front axle.
Compared with stock pads, the purchase case rests on consistent wear, quiet braking, and a complete kit. The manufacturer cites dual-layer rubberized shims for quieter stops and includes stainless-steel hardware and wear sensors, so you avoid buying those separately. Owners on user forums describe the Z17 as a comfortable everyday pad rather than a towing or track pad, and some report less initial bite than OEM. If you tow or run hard stops, consider a higher-performance Power Stop compound instead.

The manufacturer markets the Z17 Evolution as a stock-replacement pad, so it is designed to go onto the factory caliper and rotor setup. If you want new rotors too, the manufacturer offers Z17 kits that pair the same pads with rotors, so check the kit contents before ordering.
Yes, the manufacturer says the friction surface is thermally scorched for a faster break-in. Make a series of moderate stops for the first few hundred miles before relying on full-force braking.
This is a bolt-on front pad job that a home mechanic with basic hand tools and a torque wrench can usually handle. Per the manufacturer's installation guide, check the brake fluid level before starting and confirm it sits about half full at the reservoir. Torque the caliper bracket bolts and caliper bolts to your Toyota's specified values. When you push the caliper piston back to fit the new pads, watch the reservoir so fluid doesn't overflow. Apply brake lube only to the back of the pads where they contact the caliper, and keep it off the friction surface. The manufacturer recommends bleeding the brakes whenever you replace pads and rotors, so plan on that step, and bed the new pads in afterward.
