Category: Brake System

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 ... ):

th_00_cover.jpg   th_25.jpg
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).

Types

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

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

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.

th_101_3666.jpg 15114.jpgAlbum click to view

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.

Slotted Rotors

Looks schmick.

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.

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.

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:

B120

Sunny Truck staring in October 1989 has a disc brake system similar to B11/N12, which fit within 12" wheels. They use a smaller, but thicker rotor compared to the B110 disc brakes.
