Power Brake Lines

For the stock 1200 power brakes, see Brake Booster.

Hard Lines

The hard lines are 3/16" outside diameter.

* 3/16" lines (4.75 mm) with M10 metric fittings
* Cunifer lines on early 1200s for corrosion resistance
* Later 1200 utes have poly-coated steel lines

Choices

  1. get pre-made lines of various lengths and bend and install it yourself
  2. get brake line material and fittings and cut it, flare it and fit it
  3. pay a shop to make and install custom lines
  4. buy genuine brake lines from Nissan and install. The ute parts are still available, and most will fit a Sedan or Coupe.

The first two are available at the usual spare auto parts stores, or mail order from hot rod stores.

Soft Lines

Brake hoses used by Datsun 1200:

* Rear soft hose to the rear axle
* Front left soft hose to brake caliper
* Front right soft hose to brake caliper
