Category: Brake Modifications

Upgrade your 1200's brake to large 258 mm (10.15") brakes -- and keep the lightweight 1200 struts! Thanks to mklotz and morrisun at Ratsun for this great idea. The rotors are Nissan S13/S14 (Silvia/240SX/180SX) rear disks. The calipers are from Nissan N13/N14 Pulsar. You can also use 280ZX/Bluebird/S12 rear discs but they are a little heavier.

Overview

If you require vented brakes, see:

S13 Brakes for smaller, vented brakes

Bolt On Extra-large Brakes for Datsun 1200s -- no fabrication, no welding, no machining

  • 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
Uses:
* 1982-1990 Nissan B11/B12/N13/N14 calipers
* 1982-1983 Bluebird/S12/S13/S14/280ZX REAR rotors

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 reports 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 258mm solids are 7.7 pounds vs. 11 pounds for the 280ZX vented disks. Also the original 1200 struts and hubs are lighter than the 280X versions. Remember to add lightness.

Alignment: The disks push the wheel mounting face out 1/4" each side, increasing the Scrub Radius which is not good. But this is less that the 280ZX Strut Swap.

Rim Size

280ZX, S13 and S14 all used 14" rims.

This swap can fit under at least some 13" aluminum wheels. Mike and Doug tried two or three various alloy 13", and they fit. It may or may not fit under other 13" alloy wheels. They report that steel 13" wheels do not fit.

WHEEL REQUIREMENTS
* wheel backspace (back drop): 4.25" or less
* wheel barrel Minimum Inside Diameter: 12"

Wheel-Offset-copy.jpg

Some 13" wheels have a smaller I.D., and some 13s are narrower near the hub face.

Note: D275 is used by the factory Sunny Truck Disc Brakes, used with 208mm rotors to fit under 12" rims.

Details

280ZX front vented disk 252 mm, bolts to the 280ZX hub via small bolts, so won't bolt to your 1200 wheel hub:

280ZX rear solid (non-vented) disk 258 mm, simply fits over the lug nuts (captured/floating type), and it will fit over the 1200 wheel hub lugs:

Track width increase about 1/4" per side, 1/2" total.

Calipers are similar bore to the 1200 calipers, so the master cylinder reportedly does not need to be changed, nor the balance compensated for -- no need for a proportioning valve.

NOTE: These are Japan-built models all (Tokico, etc), so Australia PBR-equipped are not the same.

Brake Hoses

The calipers require banjo-type hoses. Many different hoses can be used. If you are buying new hoses, we recommend these common Nissan hoses:

1989-1994 Nissan S13/S14 "240SX"
RockAuto.com $5 each

a211b620-3082-4744-81fb-da3aacf22a29.jpg

Additionally, this set allows the choice of running calipers either in Leading or Trailing positions. Switching position is sometime done with extreme lowering. This is done by switching struts from side to side for mounting calipers in Leading position.

Rotors

258mm solid rotors.

Recommended: 258 x 9mm (lighter) from S13/S14

Also works: 258 x 10mm (heavier) from 280ZX, 910, S110/S12

S13 Rear Rotors

You can use the S13/S14 258x9 rotors with the bluehands Green caliper adapters.

These are the same diameter as 280ZX/S12/910 rotors, but are 1 mm thinner, saving 2.7 lbs per side!

S12 Rear Rotors

S12/280ZX/Bluebird 910 rotors are 1mm thicker than S13 rotors, so weigh more.

These 258mm rotors (43206-N9501/43206-N9502) are from the rear of:

Lug Studs

Since the rotors fit over the 1200 hubs, they add about 1/4" to the mounting face of the wheels. So you will need slightly longer Wheel Studs, which are common from a wreckers or buy them new.

Your local USA parts store will have some, just ask for studs for a 1993-1998 Nissan Quest.

NISMO 40222-A0220 [2" long/51mm] 
B110 or 510 FRONT

Mike Klotz recommends these studs, which the 510 guys use.

* Infiniti J30 front 1995-93
* Nissan VAN Front 1988-87, From 1/88
* Nissan QUEST Rear 1998-93, From 1/88
Compare to Stock 1200:
* Thread: M12 x 1.25

* Knurl Diameter: 13.00mm
* Thread Pitch: Right
* Shoulder Length: 10mm
* Thread Size: M12-1.25
* Length: 32mm
* Type: Serrated Stud

ARP studs (#100-7708), which are extra long

1200 rear studs are the perfect length for the front, but use a smaller diameter knurl (12.56mm), so they don't work. 280ZX Rear Studs are likewise only 12.83mm.
