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.
Caliper bolt spacing:
- ~84 mm: B110, and all 12" wheel B210 and B310
- 88.9 mm: B310 large struts for 13" wheels

| 212.5 | 40206-H1006 | B110, B210 with A12 1974, 1975 |
| 220 (AN18) | 40206-H7500 | B210 A12 1976-1978,B310 with 12" wheels |
| 232 | 40206-A1155 | B210 A13, PB110?, PB210 early? |
| 245 (AN20) | 40206-U6700 | B210 A14, B310 A14/A15, PB210 late? |
Apparently the calipers are unique for each rotor, also the strut/spindle assembly *may* be different.
