Datsun 1200s came with two brake systems:
- Drum front/drum rear - Standard trim, Deluxe trim
- Disc front/drum rear - GL, GX and optional on Deluxe
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. See Brake Swaps.
