Audi A1 Brake Discs: The Part That Pads Depend On
On the Audi A1, 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.

Audi A1 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 A1 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 A1 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.
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.
