Left-hand-drive (LHD) versions of the Datsun 1200 used a hydraulic clutch system. It is very nice, with a light, linear action.
- Extremely light clutch pedal effort, but with good feedback.

Parts
Stock USA cylinders. "Repair Kits" are also available. These include all new rubber parts, and can be used in the aluminum body is not pitted. The bore is hand-honed. Often with aluminum a kit will leak. Cast-iron cylinders may have better success.
MASTER
- 30610-24900 (superceded by 30610-24910). $111 USD
SLAVE
- Left: 30620-H1601 (superceded by 30620-H1600) $59 USD
- Right: 30620-H1600
HYDRAULIC HOSE
The hose is difficult to find in USA, except on eBay. Alternatives: lot of the brake hoses from cars with a solid rear axel will work also:
- Beck/Arnley 073-0879 (rear brake hose)
- BRAKEWARE #77001 $12 at Autozone. It's about 1.5-2 inches longer then the original, does not hang to low and bolts right up
Adjustment
This is for the 71-73 1200. The B210 (120Y) measurements are different.
- Adjust slave cylinder free play
- Adjust pedal pad height without stopper
- Adjust pedal stopper
Clutch Slave Cylinder
Adjust the free play to 5/32".
Pedal Linkage
Before adjusting the pedal linkage, first adjust the clutch release arm under the car.
The specs are:
- Pedal height: 5.57 in (141.5 mm)
- Pedal free play: 1.181 in (30 mm)
- Pedal stroke is 5.65 in (143.5 mm) with the adjustment stop (the switch in the diagram) backed off. Adjustment is made with shims for the cylinder on the firewall.
Adusting Shim
- 30611-27260 1.6 mm
- 30612-27260 0.8 mm
- 30613-27260 0.5 mm
Removable, Replacement and Bleeding
If the Master Cylinder runs dry, or when replacing it, be sure to bleed the Master Cylinder separately.
Remove the pipe & place a thumb over it for the return stroke of the pedal to prevent ingestion of air. Once the Master Cylinder is free of air you can bleed the whole system with confidence.
RHD Hydraulic Conversion
Hydraulic Clutch Master
- Girling "claypipe" master cylinder, available in 5/8" and 3/4" bores (about $70 AUD). Threads are 3/8 unc for pipe outlet and 7/16 unc for fluid in
- Nissan Urvan remote-fill tops
- A simple 90-degree bracket is needed to be made up to mount this master cylinder
Nissan Sentra Clutch Master Cylinder
- Fluid reservoir is connected to the cylinder via a rubber hose.
Remote Clutch Master Cylinder
A remote clutch cylinder may also be useful
