![[Datsun 1200 encyclopedia]](/wiki/upload/wiki.png)
Datsun 1200s came with two brake systems: all drums (Standard models), or 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.
Calipers
Calipers are used with disc brakes. Datsun B110, B210 and B310 used floating two-piston ANNET types.
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.
Rear Drum Brakes
The same rear brake drum was used 1967-1994. It is an 8" diameter cast iron drum, that fits 1-3/8 wide brake shoes. Sunny Trucks started using a different brake shoe from Oct 1989.

1978-1989 B120 ute used rear type Drum-LT20 with front type Drum2L20.
Finned Alloy Brake Drums
- The fins look like structural type, not cooling type.

Datsun Competition Dept supplied it's favoured teams with many experimental parts that were never sold over the counter. 1200s had alloy drums and calipers fitted as wellas the alloy diff heads from the wagons.
- Finned drums like these were offered by Datsun Competition in Japan.
