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
1972 USA Owners manual (Page 25 ... ):
Before driving or whenever you call at a gas-station, be sure to check ...
- Leakage and amount of fluid in brake and clutch master cylinders
- Clutch and brake operation
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
* Drum Brakes require frequent manual adjustment * Disc brakes have NO adjustment * Disc brake pads need frequent inspection * Disc brake calipers need frequent lubrication
Periodical Maintenance and Lubrication Schedule
Every 3 months/3000 miles * Check brake pedal free play If play is less than 5 or more than 15 mm, Adjust free play * Adjust the drum brakes (see Drum Brake Adjustment) * Check brake system for leaks or defects
Every 6 months/6000 miles * Check foot brake operation If travel is excessive, adjust the brakes Does the car stop straight and quickly? * Check parking brake operation Does the car hold on a hill? If the lever pulls up more than 6 clicks, adjust it * Check disc brake pads for thickness If pads are down to 1/2 mm or less, replace immediately If unevenly worn, lubricate the caliper sliding surfaces
Every 12 months/12000 miles * Lubricate foot operated pedal bushings * Check drum brake linings & drums for wear If less than 1/2 mm to the rivets, replace the shoes
Every 24 months/24,000 miles * Grease parking brake linkage * Change brake fluid
Every 30 months/30,000 miles * Overhaul brake cylinders & caliper assembly
Replacing Rotors
If the brake pads have not been replaced in time and have scored the rotors, they rotors can be removed and "turned" to like-new, or they can simply be replaced.
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 designed by Lucas Girling which 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.

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

Hardware Kit
When changing the brake pads, the old hardware can usually be re-used. But if the anti-squeal shims are missing or the springs damage, new ones can be purchased.
A disc brake "hardware kit" includes all the small parts (although individual parts are also available at parts stores).
* BENDIX H5564 * EIS H155242 * RAYBESTOS H155242 (dual kit) * RAYBESTOS H15524 (single kit) * LEE MANUFACTURING 15524 * KELSEY-HAYES HK956 * WAGNER F96607 * CARLSON 13114 * CENTRIC 11742027 * DORMAN HW13114
Some kits are dual (does both front brakes) other kits you need two of them.
The Wagner kit additionally includes new yoke springs, so you don't have to clean the old ones to make sure the Yoke (caliper plate) slides smoothly.
