Datsun 1200s came with two brake systems: all drums (Standard models), or Girling-Tokico front disc with rear drums. They were excellent brakes for the period. All are manually adjusting except non-North America Left-hand drive 1200s, which were equipped with auto-adjusting rear drum brakes.

Types
- 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. The drum system stops well enough, but the disc system has less fading going down mountain roads.
Adjustment/Maintenance

Calipers
Calipers are used with disc brakes. Datsun B110, B210 and B310 used floating two-piston ANETTE types. These were desinged by Lucas Girling who make the Anette, Babette and Colette series.
Type B110: ANNET 12/14A (1.894" cylinder inner diameter) B310 small: AN-18 (1.894" cylinder inner diameter) B310 large: Disc-AN20 (2.012" cylinder inner diameter)

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

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