OEM Part Number: 51712-A7000

Genuinely worth knowing: owners have directly reported conflicting listings between 270mm and 280mm front discs for the same car when searching by part number lookup tools — Kia's own official service manual confirms 280mm as standard, which several owners have verified by physical measurement.

Front disc, confirmed via Kia's own service manual	280mm diameter, vented, 23mm thickness
Genuine front disc references (2010-2024, shared across Kia/Hyundai platform)	Kia OEM: 51712-A7000 (also cross-referenced as 51712-1M000, 517121M000, 517122K100)
Rear discs, most trims	262mm diameter, solid, 10mm thickness
Important	Confirmed rear brakes on the Soul are discs, not drums, despite some older listings suggesting otherwise — a drum handbrake mechanism is sometimes built into the disc hub, which can cause confusion.

A Genuinely Detailed, Real Technical Explanation Worth Knowing — Kia Soul 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 Soul Brake Discs: The Part That Pads Depend On

On the Kia Soul, it's a paired system: let either one wear too far and the other suffers for it, which is why so many "just a pad change" jobs end up including discs once a mechanic actually looks.

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 Soul 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 Soul typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.
