Rear Disc Brakes

From Datsun 1200 Technical
Jump to navigation Jump to search

The stock rear brakes are fairly good, using large (for such a light car) 8" x 1.75 brake shoes. Make sure the brakes are clean and adjusted correctly every 3 months. Using a performance pad will improve it. But for coolness sake... read on.

Overview

There are two main steps to adding disc brakes to a rear axle:


  1. Fitting the brake rotor to the axles
  1. Fitting a caliper bracket to the axle housing


Example: Bracket for Nissan S30 rear for R32 calipers

(similar to Nissan 44155-N3202 but made out of aluminum)

R31 Australia

You can fit the Australian-built R31 Pintara/Skyline disc brakes onto H145/H150 or H165 axle assemblies.

Pitroad Kit


Pitroad rear disc adapters for B110


  • Uses late model S130 (280ZX) caliper and rotor (I think it says it uses Skyline HR30 adapters)


44155-N3202 machined with: * 4 new holes for the H145 pattern * an insert for the smaller diameter axle tube interface

Andy: The Pitroad rear disk brake kit only includes the brackets, E-brake cables, axle sleeve thingys, clips, rubber brake hoses, and axle bolts. You supply the calipers, pads, and rotors from an 82-83 280ZX, as well as new oil seals for the axles, wheel bearings, etc. It's pretty straight forward, you have to pull off the old drum brake assemblies and put on their new bracket just before you put the new wheel bearings in. You do have to drill two really small holes on the E brake cable holder, but other than that it's really easy.

In general, 1982 280ZX and 300ZX has a smaller rear caliper with larger pads than the early (1979-1981) 280ZX. The offset of the early vs. late caliper is quite different.



AE86

To fit AE86 calipers on B110 rear axle housing, create an adapter.

H165


Sentra Rotor Adaption

3rotor designed bracket for box-shape Sentra (Nissan Sunny B12) calipers, to fit 240mm rotor. The same bracket can also fit Maxima 250mm rotor.


The rotors slip over the hub (floating type). The pattern must be re-drilled to 4 x 4.5" (4 x 114.3 mm) before it will slip on. Center hole also needs enlarging.

See Rear Axle Swaps


These include rear disc brakes:


  • Complete rear end off a Toyoda with disk brakes (Corolla AE86)
