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
See: * Drum Brake Adjustment * Disc brakes need no adjustment
Replacing Rotors
The brake rotor bolts to the hub on disc brake models. It is retained by four bolts to the hub. A press is not required as the joint is not an interference fit.
After removing the hub from the strut, unbolt the four rotor-retaining bolts. If the rotor does not separate easily, get 2 house bricks and place them on concrete end up. Place the disc/hub between the bricks wheel face down with the rotor face on the bricks. Using a hammer strike the inner wheel bearing seal carrier area lightly moving around its full circumference. This should loosen the joint.
- Remove the front Wheel in question
- Using a screwdriver, carefully pry the brake pads away from the rotor a little bit
- Using a length of twine or wire, tie the caliper to the spring, so that it won't fall when the caliper is unbolted
- Unbolt the caliper, and lift up and away from the rotor
- Tap the grease cap off, and remove the large spindle retaining nut
- Pull the hub & rotor straight off
To replace the hub after bolting on the new rotor, see Wheel bearings.
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.

Front Drum Brakes
1200 DX and STD trim received front drum brakes (GL and GX were fitted with Disc Brakes). It uses two cylinders, unlike the rear drums which have one cylinder.
* Wheel cylinders: 13/16 inch bore diameter
