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.

Daily Care

Observe the level of fluid visible through the plastic reservoir of the master cylinder (no need to remove the cap).

• If it is at or below the fill line, top up with DOT 3 Brake/Clutch fluid.

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.

full

album

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.

1. Remove the front Wheel in question
2. Using a screwdriver, carefully pry the brake pads away from the rotor a little bit
3. Using a length of twine or wire, tie the caliper to the spring, so that it won't fall when the caliper is unbolted
4. Unbolt the caliper, and lift up and away from the rotor
5. Tap the grease cap off, and remove the large spindle retaining nut
6. 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 designed by Lucas Girling whicg designed the Anette, Babette and Colette series.

1969 Annette: Fixed twin-piston with floating caliper (yoke type), as used by B110/B210/B310
1974 Colette: Single-sided (fist type) floating caliper as used by S13

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)

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

Brake Lines

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

Rear Drum Brakes

B120

Front Disk Brakes from 8910. These are unique as they fit the same strut as the former drum brake setup.

Master Cylinder

Master cylinder has two bolts in horizontal plane; previous drum brake system used two bolts in vertical plane (like B110).

Front Discs

Sunny Truck staring in October 1989 has a disc brake system similar to B11/N12.
