Upgrade your 1200's brake to large 268 mm (10.565 inch) brakes -- and keep the lightweight 1200 struts! Thanks to mklotz and morrisun for this great idea. The rotors are 280ZX rear disks. The calipers are from 1980s Pulsar and Sentra/Sunny.

Overview
Bolt On Extra-large Brakes for Datsun 1200s -- no fabrication, no welding
- Lightweight disk rotors
- keep your lightweight 1200 disk struts
- fits under 13" aluminum wheels & 14" steel wheels
- No modifications needed to master cylinder
Will fit under 16 & 17" wheels too for you new-school fans
Doug Morrisun from Oregon came up with this idea: the lightest, largest brakes that would fit on the stock struts. To keep weight down, his idea was to use a solid rotor. Non-vented. He says that for a light 1200 street vehicle there is no fading.
Remove the 1200 disks from the hub, then put the 1200 hub back on the car.
you will need slightly longer wheels studs, from a wreckers or buy them new
Slip the new disks over the hub
Here's the trick: it needs a caliper spacer/adapter:
Weight: The 280ZX solids are 10.5 pounds vs. 11 pounds for the vented disks. However, you keep the original 1200 struts and hubs. Hopefully it is lighter...
Alignment: The disks push the wheel mounting face out 1/2" each side, increaseing the Scrub Radius which is not good. But this is less that the 280ZX Strut Swap (hopefully).
Details
280ZX front vented disk, bolts to the 280ZX hub via small bolts, so won't bolt to your 1200 wheel hub:
280ZX rear solid (non-vented) disk, simply fits over the lug nuts (captured/floating type), and it will fit over the 1200 wheel hub lugs:
Parts & Specifications
Caliper
The calipers are from:
- Nissan B11/B12 (Sentra/Sunny)
- Nissan Pulsar N12/N13
Wreckers are full of these, but re-manufactured are only $21 each at
These are Japan-built models all (Tokico, etc), so Australia PBR-equipped are not the same.
Adapter
mklotz of Datsun NL320 disk retrofit fame is making some sets of the adapters. In fancy colors.
Rotor
The rotors are from:
- 1982-1983 S130 (280ZX)
- 1982-1988 S110/S12 (200SX)
- 1982-1984 910 six (Maxima)
These are Japan-built models all, so Australia PBR-equipped are not the same.
Rotors are only $20 each new at http://www.rockauto.com/catalog/x,carcode,1209316,parttype,1896
