OEM Part Number: 1K0615601AA

Accuracy note: Octavia disc sizes span a wide range (230-340mm) across generations and trims, since vRS performance models use significantly larger discs than standard cars — always confirm your exact generation, engine, and trim before ordering.

Current Mk4 (2019 onwards), standard trims	312mm diameter, vented, 25mm thickness, 22mm minimum
Mk2 (2004-2013), rear discs	272mm diameter, solid, 10mm thickness, 8mm minimum — OEM: 1K0615601AA
vRS models (most generations), front discs	312mm diameter, vented, 25mm thickness, 23mm minimum — significantly larger than standard trims
Important	vRS front and rear discs are genuinely different components from standard-trim discs despite sharing the same overall diameter in some cases — always check thickness and bore diameter, not just outer diameter, before ordering.

Confirmed: A Genuine, Well-Documented VW Group Corrosion Pattern — Skoda Octavia Brake Discs

Across Skoda and wider VW Group owner forums, one theme repeats with remarkable consistency: OEM brake discs have a documented reputation for corroding and pitting considerably faster than quality aftermarket alternatives, particularly on the rear axle. Multiple owners who've switched to reputable aftermarket brands (Pagid and Napa Proformer both specifically mentioned across VW Group forums) report the corrosion problem disappearing entirely after fitting, suggesting this is genuinely more about the OEM disc material and coating than an inevitable characteristic of the car itself.

A genuine tip directly from a VW Group dealer, worth trying: braking a little harder toward the end of a journey after driving in rain helps keep the discs hot enough to resist corrosion building up — rear discs in particular do less work than the fronts and don't always get hot enough on their own to shed off moisture and light surface rust before it takes hold.

It's worth knowing dealers frequently treat corrosion-related disc replacement as chargeable "wear and tear" excluded from warranty, even on cars just a couple of years old with genuinely low mileage — but this isn't always the final word, and escalating a formal complaint in writing to Skoda customer services has resulted in goodwill contributions for other VW Group owners facing the same pattern.

The Part That Pads Depend On

Discs and pads work as a pair, and neglecting one tends to accelerate wear on the other — which is exactly why worn discs so often get discovered during what was meant to be a routine pad change.

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.

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