|---|---|
| Disc sizes & variants | One front size only, 258 mm (quoted as 257.5 mm by some brands) x 22 mm vented with four holes; every petrol and diesel DJ shares it. The 255 mm discs are solid rears. |
| Genuine (OE) numbers quoted | D0YN-33-29ZA (genuine front disc number for this model — confirm via VIN, as several disc sizes exist) |
| Fitment notes | All DJ models get the same 258 mm vented front disc; minimum thickness is 20 mm (21 mm on the 23 mm Hella). Height is 44 mm and the hub is four-stud, so do not confuse it with the five-stud Mazda 3 disc. |
Confirmed: Real Technical Bulletins Addressing This Exact Issue — Mazda 2 Brake Discs
This is genuinely worth knowing if you're seeing premature rear disc corrosion or uneven wear: Mazda has issued confirmed technical service bulletins specifically addressing poor rear brake disc wear on related models. Genuinely worth knowing why this happens: forum discussion points toward the rear brakes being applied harder and sooner than the fronts as a result of how Mazda's traction control system balances braking, combined with genuinely smaller rear pads that some owners believe may be under-specced.
It's also genuinely worth knowing about a real, honest, and rather damning consumer account: one owner, facing premature rear disc corrosion at just two years old, was told directly by Mazda UK that they were "washing their hands of it," declining warranty coverage and calling it fair wear and tear.

Mazda 2 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 2 typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.
