Audi A5 Coupe Brake Discs: Specs, Fitment & Wear Symptoms

On the A5, what's commonly called "warped discs" is genuinely almost always uneven pad deposits on related models, not physical warping.

Generation covered: this guide is for the second-generation A5 Coupe (F5 platform, 2016–2024) — the two-door coupe discontinued when Audi renamed the A4 saloon to A5 in 2024. These are entirely different cars despite sharing a name; if your car is a four-door saloon or estate bought new since 2024, this guide does not apply to it. Check your logbook or VIN if you're unsure which car you have.

The Part That Pads Depend On

On the Audi A5 Coupe, 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.

OEM Part Number: 4G0-615-301-AF

Accuracy note: confirmed for early F5-generation cars (2014–2017) with the larger 345mm front rotor — Audi may have superseded this reference on later cars, so confirm against your VIN regardless of registration year.

Front rotor, 345mm (2014–2017)	Audi OEM: 4G0-615-301-AF (also referenced as 4G0615301G, 4G0615301Q)
Front rotor, 320mm (smaller-brake trims)	Different reference to the 345mm version — confirm your rotor size
S5 / RS5	Larger, high-performance rotor — not interchangeable with standard A5 discs

The A5 Coupe was offered with two different front rotor diameters (320mm and 345mm) depending on trim and brake package, and this number is shared with the mechanically related A4, A6, S4 and S5 given the platform they have in common. Confirm your rotor size before ordering.

Audi A5 Coupe 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 A5 Coupe typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.

A Genuinely Useful Piece of Context Worth Knowing About Brake Vibration — Audi A5 Coupe Brake Discs

If you're facing a vibration under braking that's been diagnosed as warped discs, this is genuinely worth knowing: among experienced Audi owners, there's a widely repeated consensus that true disc warping is actually quite rare, with the vibration almost always caused by uneven pad material deposits on the disc surface instead. It's genuinely worth trying braking firmly from around 70mph down to 10mph, repeated several times without letting ABS intervene, to remove this build-up before assuming discs need replacing.

A genuinely alarming, honest account worth knowing about replacement discs: documented cases describe original factory discs lasting tens of thousands of miles without issue, only for a replacement set to develop the exact same vibration within just a few hundred miles, suggesting the fitting process itself can be the genuine cause.

It's also genuinely worth knowing that a dealer refusing warranty cover for a brake disc issue, citing ordinary wear, has in documented cases been overturned by escalating directly to the manufacturer's UK customer service.
