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.

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

See:
* Drum Brake Adjustment
* Disc brakes need no adjustment

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.

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

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.
