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.

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.

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.

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 whicg designed the Anette, Babette and Colette series.

1974 Colette: Single-sided (fist type) floating caliper as used by S13

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).

RockAuto.com

* EIS H155242
* RAYBESTOS H155242 (dual kit)

* 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.

120Y

A12-powered B210 uses small suspension similar to 1200.

1974-1975: used the same brakes as Datsun 1200 (212 mm disc)
1976-1978: AUS changed to larger 220 mm rotors
           EUR continued with 212 mm rotors

NOTE: 120Y for Germany, Switzerland and Austria uses large suspension like USA B210. Possibly all LHD B210?

Australian-assembled late 120Y used a locally sourced PBR caliper, using a adapter plate:

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.
