OEM Part Number: 1S0615301L (genuine front disc — confirm via VIN) — aftermarket front discs Brembo 09.7011.31 / Bosch 0 986 479 776

Accuracy note: Covers the Volkswagen Up! (2011-) 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.

Front brake discs (aftermarket)	Brembo 09.7011.31 (256 x 22 mm, vented, 4 holes, coated, high-carbon, min 19 mm); Brembo 09.B975.11 (256 x 22 mm, vented, 4 holes, coated, high-carbon, min 19 mm); Bosch 0 986 479 776 (256 x 22 mm, vented, 4 holes, oiled, high-carbon, min 19 mm, ECE-R90); TRW DF6252 (256 x 22 mm, vented, 4 holes, painted, min 19 mm); ATE 24.0122-0281.1 (256 x 22 mm, vented, 4 holes, coated, high-carbon, min 19.0 mm); Zimmermann 600.3250.20 (256 x 22 mm, vented, 4 holes, coated, high-carbon, Coat Z, min 19 mm); Zimmermann 600.3250.52 (256 x 22 mm, vented, drilled, 4 holes, coated, high-carbon, Sport Coat Z, min 19 mm); Zimmermann 600.3265.20 (288 x 25 mm, vented, 4 holes, coated, high-carbon, min 22 mm)
Disc sizes & variants	The standard front disc is 256 x 22 mm vented on a four-stud 100 mm pattern with a 65 mm centre bore, used across the 1.0 petrol, e-up! and up! GTI-era range. A 288 x 25 mm four-stud disc (Zimmermann 600.3265.20) is also listed; this larger size is the fitment for the up! GTI. Meyle 115 521 0006 is quoted at 257 mm, which is the same standard disc.
Genuine (OE) numbers quoted	1S0615301L (genuine front disc number for this model — confirm via VIN, as several disc sizes exist)
Fitment notes	Minimum thickness is 19 mm for the 256 mm disc and 22 mm for the 288 mm disc. The Ridex 82B0493 and Stark SKBD-0022212 uncoated discs are marked as usable only on cars built up to November 2016. All front discs here are four-stud; do not confuse with five-stud 256 mm Polo discs.

Confirmed: A Genuinely Widespread, Well-Documented VW Corrosion Pattern — Volkswagen Up! Brake Discs

Across VAG owner forums, one theme repeats with remarkable consistency: VW's own-brand OEM brake discs have a documented reputation for corroding and pitting considerably faster than quality aftermarket alternatives, particularly on the rear axle. Multiple owners who've switched to reputable aftermarket brands (Pagid and Napa Proformer both specifically mentioned) report the corrosion problem disappearing entirely after fitting, suggesting this is genuinely more about VW's chosen disc material and coating than an inevitable characteristic of the car itself.

A genuine reason rear discs corrode faster, worth understanding: rear brakes generally do less work than the fronts, and cars fitted with adaptive cruise control (which can apply light rear-biased braking automatically) or a hybrid/plug-in hybrid drivetrain (where regenerative braking reduces how often the friction brakes are used at all) make this worse still. A genuinely useful trick some owners use: deliberately braking a little harder than usual for a week or two, including using speed bumps as an opportunity, can clean up light surface corrosion before it becomes a genuine problem.

It's worth knowing dealers frequently treat corrosion-related disc replacement as chargeable "wear and tear" excluded from warranty or maintenance plans, even on cars just a couple of years old with low mileage — but this isn't always the final word. Real cases exist of owners successfully obtaining a refund after VW head office intervened following a formal written complaint, when a local dealer initially refused to honour a maintenance plan covering brake repairs. If you believe corrosion this early genuinely reflects a material issue rather than ordinary wear, escalating in writing to VW customer services is a genuinely worthwhile step before accepting the dealer's first answer.

Volkswagen Up! Brake Discs: The Part That Pads Depend On

On the Volkswagen Up!, 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.

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