Peugeot 3008 Brake Discs: Specs, Fitment & Wear Symptoms

A genuine, dealer-confirmed fault causes brakes to overheat by not releasing fully — plus a real story of how cleaning and hard braking saved a full disc replacement bill.

OEM Part Numbers

Genuinely useful technique worth knowing: the 3008 has used at least seven different disc diameters across its production run (268mm to 330mm), depending on engine and gearbox. Peugeot's own ServiceBox VIN lookup tool has been directly confirmed by owners as a reliable way to get a definitive answer, rather than guessing from engine size alone — a dealer or independent specialist can run this for you using your VIN.

Confirmed via VIN lookup, 1.6 HDi manual	283mm diameter — Peugeot OEM: 9803918180
Confirmed via VIN lookup, alternative spec	304mm diameter — Peugeot OEM: 4249K1
Rear discs, most common spec	268mm diameter, solid, 12mm thickness, 10mm minimum
GT/higher-performance trims	330mm diameter, vented — a genuinely larger specification than standard trims

A Genuine, Confirmed Fault: Brakes That Don't Fully Release

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.

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 3008 typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.

Fitment & Compatibility

Disc size and specification vary by trim and braking package on the 3008. Always confirm the exact disc size and design fitted to your specific trim before ordering. Whether you're sourcing a replacement brake discs for your Peugeot 3008 from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying.

Common Wear Symptoms

Vibration or pulsing through the brake pedal — often a sign of warped discs, usually from excessive heat build-up.
Visible grooves or scoring on the disc surface — indicates the pads have worn down to metal and are cutting into the disc itself.
Squealing that persists even with new pads — can point to a rough or glazed disc surface needing replacement.
Longer stopping distances despite good pads — worn or warped discs reduce effective braking surface contact.

DIY Replacement Difficulty

This is a moderate DIY job for someone comfortable with basic tools and a jack, typically done alongside a pad replacement since the caliper needs removing either way. Rear discs on cars with an electronic parking brake may need a specific tool or diagnostic device to retract the caliper. Expect 45–90 minutes per side including pads.

OEM vs. Aftermarket

Reputable aftermarket brake discs are widely regarded as safe and effective, provided they carry proper certification and match the correct size and design for your trim. As with pads, this is a part worth not cutting corners on — budget unbranded discs are a common source of premature warping and noise complaints.
