OEM Part Number: confirm via VIN — front discs (aftermarket) Brembo 09.8303.11 / Bosch 0 986 479 193

Accuracy note: Covers the Peugeot 508 (2011-2018) as listed in the UK aftermarket catalogues. Front brake discs are sold by diameter and thickness, and most models have two or three disc sizes depending on engine, brake size and trim — a 278 mm disc will not fit a car built with 300 mm brakes, so the caliper carrier and the disc must match. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with diameter x thickness in mm; genuine numbers are shown only where a listing quotes one. Measure the old disc or check the brake size against your VIN before ordering, replace discs in pairs with new pads, and scrap any disc at or below its minimum thickness.

A Genuine, Confirmed Fault: Brakes That Don't Fully Release — Peugeot 508 Brake Discs

If you're noticing a burning smell, a wheel that feels unusually hot after driving, or a wheel making noise that comes and goes seemingly at random, this is worth checking directly before assuming worn discs or pads: a genuine, dealer-confirmed fault exists where the brakes don't release fully from the disc after being applied, causing exactly this kind of overheating on one or more wheels. This has been documented as an out-of-warranty repair even on cars only around 1.5 years old, with a labour cost commonly in the £60-80 range. If you notice a wheel running hot or smelling of brakes after ordinary driving, it's worth raising this specific fault by name with a technician rather than assuming it's simply wear.

A genuine, real story worth knowing before paying for a full disc replacement: one owner was told at just 20,000 miles that an apparently warped front disc needed both discs and pads replaced, since it wasn't considered a warranted part. Before paying for this, they tried cleaning the pads and reapplying copper grease, then took the car for a drive specifically doing several rounds of hard braking once it was safe to do so — this resolved the vibration completely and saved what would otherwise have been a substantial bill. Rust building up on a disc's clean, unworn area (common on lower-mileage cars, or after the car's been standing in wet weather) can produce a vibration that feels exactly like a warped disc but isn't one.

Peugeot 508 Brake Discs: The Part That Pads Depend On

On the Peugeot 508, 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.

Peugeot 508 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 508 typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.
