Datsun 1200 used two basic brake master cylinders:
- 11/16 diameter safety split circuit, used with disc-brake models
- single reservoir, used with economy drum-brake models
Some club members are using a 13/16 master cylinder from the B310. This increases pedal effort, but reduces pedal travel for a "tighter" feel. Discussion: Is anyone running a 13/16 master cyl w/out a booster?
Adjustment
B110 has a non-adjustable master cylinder. When re-installing or after fluid has drained, do the following:
- Perform Brake Bleeding, including "bench bleeding" of the master cylinder.
- Tighten the master cylinder retaining bolts to 1.5-1.8 kg-m (10.8 to 13.0 ft-lb) torque.
- Adjust brake pedal height.

Rebuild Kits
Note that Tokico and Nabco internals are different. So while you can interchange the whole Master, a rebuild kit needs the specific kind.
