The PowerStop 17-2139 is a front Z17 Evolution ceramic brake pad set that ships with its own hardware, aimed at Audi Q5 owners who want quieter, cleaner stopping for daily driving. The friction compound is a low-dust ceramic, and the manufacturer pairs it with OE positive-mold pad construction, a thermally scorched pad surface for faster bedding, and dual-layer rubberized shims to damp noise. Chamfered and slotted pad edges are included for noise-free braking, and premium stainless-steel hardware is supplied for a complete front-axle pad swap.
Compared with stock pads, the manufacturer positions the Z17 as an upgrade that keeps wheels cleaner and braking quieter without a race-oriented compound, which suits a daily-driven Q5 well. Compared with budget pads, the powder-coated backing plate is meant to resist rust and extend pad life, and the stainless hardware helps keep caliper slides and pins working smoothly at each service. Q5 front brake setups are not identical across years and trims, so owners on user forums report that some Q5s use Brembo front calipers and that front rotor diameters vary. Confirm your caliper type and rotor size before ordering, and search for PowerStop 17-2139 Audi Q5 front Z17 Evo ceramic pads if you are comparing fitment notes.
The fitment for this specific part number could not be fully confirmed against the manufacturer's application data during research. Owners on user forums report that Q5 front setups differ, with some models using Brembo calipers and several front rotor diameters in use, so match your caliper and rotor to the application before buying.
The manufacturer's Z17 Evolution guidance calls for 30 decelerations from 30 mph to 5 mph, with 30 seconds of cooling between each stop. It also notes that a resin smell during the first hot stops is normal.
This is a manageable front brake job for a home mechanic with a basic socket set, a torque wrench, a C-clamp or caliper piston tool, and a wire or bucket to support the caliper. Owners on user forums suggest unplugging and removing the wear sensor before pulling the caliper, partially driving out the caliper guide pins, and hanging the caliper so it does not rest on the brake hose. Remove the rotor only after the caliper is clear, and pump the brake pedal gently after reassembly before driving. Use the included stainless hardware and avoid over-tightening the caliper bracket bolts. Plan on a proper bed-in afterward to get the pads to their rated performance.
