Nissan Leaf Brake Discs: Specs, Fitment & Wear Symptoms
A genuinely important EV-specific consideration: regenerative braking means discs work less overall, so a normal amount of surface rust can look more pronounced simply from less everyday use.

OEM Part Number: 40206-4BA0A (genuine front disc — confirm via VIN) — aftermarket front discs Brembo 09.C544.11 / Bosch 0 986 479 091
| Front brake discs (aftermarket) | febi bilstein 108392 (295 x 26 mm, vented, 5 holes, coated, minimum thickness 24 mm, 2 mounting bores); Brembo 09.C544.11 (283 x 28 mm, vented, 5 holes, coated, minimum 26 mm); Bosch 0 986 479 091 (283 x 28 mm, vented, 5 holes, oiled, minimum 26 mm); A.B.S. 18495 (283 x 28 mm, vented, 5 holes, coated); Samko N2052V (283 x 28 mm, vented, 5 holes) |
|---|---|
| Disc sizes & variants | Two front sizes appear: 283 x 28 mm and 295 x 26 mm. Only the febi 108392 is explicitly marked as a front-axle disc; the 283 x 28 mm discs are listed for this model without a stated fitting position but match the front disc carried over from the first-generation Leaf. |
| Genuine (OE) numbers quoted | 40206-4BA0A (genuine front disc number for this model — confirm via VIN, as several disc sizes exist) |
| Fitment notes | Rear discs are 292 x 16 mm vented across the board (Zimmermann 200.2536.20, ATE 24.0116-0119.1, Bosch 0 986 479 D20 high-carbon, Brembo 09.C929.11, Ferodo DDF2786C, TRW DF6789). |
A Genuinely Important EV-Specific Consideration Worth Knowing — Nissan Leaf Brake Discs
It's genuinely worth understanding how regenerative braking changes disc wear patterns on the Leaf compared with a combustion-engined car: since the electric motor handles the majority of everyday deceleration, the friction discs and pads see considerably less use overall. While this sounds like good news for longevity, it has a genuine downside — discs that go through fewer normal braking cycles have less opportunity to naturally clear light surface rust through everyday use, meaning a genuinely normal amount of cosmetic surface corrosion can look more pronounced or persistent than on a comparable combustion-engined car simply because the discs aren't being worked as often.
It's also worth knowing that because the discs work less overall, they can occasionally develop light corrosion or scale on the unused portions of the braking surface — worth having them inspected periodically even if the car feels like it's stopping perfectly normally, since visual inspection catches this in a way that everyday driving feel doesn't.

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