OEM Part Number: 517122T000 (genuine front disc — confirm via VIN) — aftermarket front discs Brembo 09.D428.11 / Bosch 0 986 479 E42

Accuracy note: Covers the Kia Sportage (2016-2022) as listed in the UK aftermarket catalogues. Front brake discs are sold by diameter and thickness, and most models have two or three disc sizes depending on engine, brake size and trim — a 278 mm disc will not fit a car built with 300 mm brakes, so the caliper carrier and the disc must match. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with diameter x thickness in mm; genuine numbers are shown only where a listing quotes one. Measure the old disc or check the brake size against your VIN before ordering, replace discs in pairs with new pads, and scrap any disc at or below its minimum thickness.

Front brake discs (aftermarket)	Brembo 09.D428.11 (305 x 25 mm, vented, 5 holes, coated high-carbon, with bolts, min 23.4 mm); Brembo 09.C245.11 (320 x 28 mm, vented, 5 holes, coated high-carbon, with bolts, min 26.4 mm); Bosch 0 986 479 E42 (305 x 25 mm, vented, 5 holes, coated high-carbon, ECE-R90, with bolts, min 23.4 mm); Bosch 0 986 479 A21 (320 x 28 mm, vented, 5 holes, coated alloyed/high-carbon, with bolts, min 26.4 mm); TRW DF6497S (305 x 25 mm, vented, 5 holes, black painted, min 23 mm); TRW DF7592 (320 x 28 mm, vented, 5 holes, black painted); ATE 24.0128-0258.1 (320 x 28.1 mm, vented, 5 holes, coated alloyed/high-carbon, min 26.4 mm); Delphi BG4931C (305 x 25 mm, vented, 5 holes, coated, R90)

Genuine (OE) numbers quoted	517122T000 (genuine front disc number for this model — confirm via VIN, as several disc sizes exist)
Fitment notes	Minimum thickness is 23.4 mm for the 305 mm disc and 26.4 mm for the 320 mm and 300 mm discs. None of the listed front discs are drilled. Ferodo, Textar and Zimmermann are not listed. The Ridex 82B0251 (300 mm, uncoated) is listed for cars built up to November 2016.

A Genuinely Detailed, Real Technical Explanation Worth Knowing — Kia Sportage Brake Discs

If you're hearing a specific rubbing noise particularly noticeable after heavy braking downhill, this is genuinely worth knowing: a documented case on a related model traced this exact symptom to a steel spring that joins the two halves of the caliper, rubbing against a corrosion buildup at the edge of the disc, worsening as the disc heats up and expands.

A genuinely useful, real maintenance point worth knowing: a full strip-down and clean of the calipers typically isn't included as part of a standard annual service — worth having this done specifically every two to three years, since crud and rust building up in the pad guides can restrict proper movement and lead to uneven wear.

It's also genuinely worth knowing an honest consumer point: already-corroded discs on a genuinely new car can potentially indicate they weren't of merchantable quality, worth pursuing as a warranty claim. It's also worth knowing that a short drive after washing the car helps dry discs out properly.

Kia Sportage Brake Discs: The Part That Pads Depend On

On the Kia Sportage, discs and pads don't wear independently — neglect one and the other degrades faster too, which is exactly why what starts as a routine pad change frequently turns into a disc replacement as well.

Before you buy: disc size and design vary by trim, engine size and whether your car has the standard or "sport" brake package. Always confirm against your VIN before ordering.

Kia Sportage Brake Discs: What They Do

Brake discs provide the surface the brake pads clamp against to slow the car, converting momentum into heat through friction. Larger, sportier trims of the Sportage typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.
