|---|---|
| Disc sizes & variants | The front disc is nominally 258-260 x 22 mm across the range; the 258 mm and 260 mm references are the same Renault-Nissan Clio-derived size quoted to different tolerances by different brands. A single 280 x 22 mm TRW DF4294 is also listed as a front disc, which is the larger disc used on higher-output versions. Rear discs listed are 292 x 16 mm vented, although most K14 Micras have rear drums. |
| Genuine (OE) numbers quoted | febi bilstein 39477 is listed for OE number 77 01 210 081 SK |
| Fitment notes | Drilled (Brembo 09.9078.1X and 09.9078.2X) and slotted (Brembo 09.9078.75) versions of the 258-260 mm disc are also available. The K14 shares its 258/260 x 22 mm front disc with the Renault Clio IV, which is why Renault OE numbers appear. |
A Genuinely Useful Distinction Worth Knowing: Normal Surface Rust vs Genuine Corrosion — Nissan Micra Brake Discs
Seeing light rust on discs, particularly on a car that's sat unused for a few days, is genuinely normal and nothing to worry about — one or two braking cycles typically clears surface rust from the contact area. However, genuinely excessive corrosion — rust extending noticeably inside the alloy wheels themselves, or discs looking like the car has been left standing in a wet field for weeks — is a different matter entirely and worth raising with a dealer, particularly on a young car with low mileage.
It's also worth understanding a genuinely real, broader industry context: since asbestos was phased out of brake pad friction material, harder pad compounds have become standard, and discs are now more deliberately treated as the more sacrificial, wear-prone component of the pairing.

Nissan Micra Brake Discs: The Part That Pads Depend On
On the Nissan Micra, 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.
Nissan Micra 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 Micra typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.
