Datsun 1200s came with two brake systems:
- Drum front/drum rear - Standard trim, Deluxe trim
- Disc front/drum rear - GL, GX and optional on Deluxe
The 1200 front-disc/rear-drum system was good for 1971. In fact, stopping power was better than most 'muscle cars' of the era. However, if you have a drum/drum system, you'll want to upgrade to disc/drum. See Brake Swaps.
Rotor Sizes
| Dia. (mm) | Part Number | Source |
| 212.5 | 40206-H1006 | B110, B210 with A12 1974, 1975 |
| 220 (AN18) | 40206-H7500 | B210 A12 1976-1978,B310 with 12" wheels |

Apparently the calipers are unique for each rotor, also the strut/spindle assembly *may* be different.
