Audi Q5 Brake Discs: Specs, Fitment & Wear Symptoms

On the Q5, what's commonly called "warped discs" is genuinely almost always uneven pad deposits on related models, not physical warping.

OEM Part Number: 8R0615301F

Genuinely important warning for SQ5 owners: one documented owner fitted aftermarket Bosch discs that were confirmed to fit by the retailer, only to find the hub bore was too large — the seized original discs needed a hammer and drift to remove, and genuine Audi parts (a "floating spoke" design that dissipates heat differently) were ultimately required at around £415 per pair. Worth checking hub bore diameter specifically, not just outer diameter, before buying aftermarket for a higher-performance variant.

Audi Q5 Brake Discs: The Part That Pads Depend On

On the Audi Q5, because discs and pads wear as a pair, neglecting one speeds up wear on the other — which explains why a routine pad change so often turns up discs that are further gone than expected.

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.

Audi Q5 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 Q5 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 Q5 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.
