Better Brakes

Here are some considerations of a braking upgrade:

  • Bigger caliper and brake pads will slow down car more quickly
  • Larger-diameter disc brake rotor will improve braking power and sensitivity
  • Vented rotors will improve repeated stops (less brake fade because the rotors can shed heat faster)
  • Coilover swaps permit wider tires

Notes:

  • Slotted/drilled rotors are unnecessary and can often weaken the rotors, but may be useful in some racing applications (check with your brake vendor for their suggestions)
  • Large tires will improve brake contact patch thus are a huge part of increased braking performance
  • A dual master cylinder is safer than a single one. See Brake Upgrades.
  • Front and rear caliper/cylinder ratios should match the application of the car weight bias, brake and tire sizes (See Brake Bias). Otherwise, a brake proportioning valve will be needed to prevent premature lockup
  • Bigger tires. Yes, this has a big effect on brakes, because more rubber on the road lets you stop faster before the car skids. 1200 accept 185-width on front, 205-width on back (if the wheels have appropriate backspacing)

Slotted Rotors

RDA can supply standard 1200 rotors with slots if you ask for them. Mine cost me $290 for the pair.

Some say slotting and drilling have no performance benefit but can increase the likelihood of cracking. But they look schmick.

1200 Disc Swap

If your 1200 has front drum brakes, take note that disc brakes are:

  • easier to work on
  • More resistant to fading -- safer after repeated stops (they dissipate heat far better)

Swapping 1200 drums for discs is easy.

See main article: 1200 Disc Brake Swap

front brake upgrade 1200 ute i used a sunny strut leg unbolted the disc off the hub and bolted a cc lancer vented disc to that and then a used a 4pot caliper off a 80mod volvo which bolts strait onto the sunny strut leg

front brake upgrade 1200 ute

  • 1200/120Y struts
  • B310 (sunny) hubs, outer edge turned down to 140mm

Better Brakes for HB210

See Aerospace Brake Kit for A14-powered B210 struts on Ratsun.net

http://community.ratsun.net/topic/40004-datsun-front-aerospace-brake-kit-installation

These fit the 2" North America B210 strut/hub assembly (same as PB210 Japan).

280ZX Brake Upgrade

Upgrade your 1200's brake to large 258 mm (10.15") brakes -- and keep the lightweight 1200 struts! No machining required.

S13 Brakes

13 (1989-1993 Silvia, 180SX, 200SX) brakes can be modified for use on Datsun 1200 struts. With an adapter plate (Kev Rowley special) you can use Silvia calipers and rotors on a 1200/120Y disc brake strut. .

Better Brakes for Z/ZX Struts

After you have installed Z or ZX struts, you may be interested in fitting bigger brakes to them.

See main article: Better Brakes for Z/ZX Struts

Hilux 4-piston Calipers

Toyoda Hi-lux and Landcruisers come with 4-piston calipers. Can be fitted over a variety of rotors.

Skyline Twin-Piston

Lightweight twin spot calipers from R32/R34 skyline rear for either 1000 or 1200 race conversion.The rotors it uses are perhaps the lightest 297mm rotor around as its only 16mm thick or 3mm thicker than solid Sigma GE rotors.

Rotor/disc DBA part no: 908
Diameter: 297mm 
Height: 63mm
Thickness: 18mm (16 min)
Centre hole: 68 (2mm machined for 70mm hubs)
The 5 stud rotor can easily be re-drilled for 4 stud

R34

R32 GTS

Magna Rotor

A10 Stanza/B310 Sunny strut with Mitsubishi Magna/Verada rotors. Magna was an Australia-assembled product 1985-1991.

You can use GM Holden Commodore VL Turbo caliper with 275mm rotors

Or use corona hubs, 250 rotoros and 60-series cruiser calipers, fit under 13" wheels with a 1mm grind

250mm rotors and 4pots under 13" rim

sunny struts, swapped left to right with Mistubishi Verada vented rotors and commodore calipers. I've also heard of rx7 4-spot calipers being used. All this fits under 13" rims.

sunny struts ,magna discs, girlock calipers...

Caliper is HZ holden PBR alloy (e.g early Holden Kingswood) with Verada disks. You will need 15" rims or bigger to fit over this change.

Brake Swap Notes

Twin piston sumitomo calipers for sale, go straight onto stanza struts with the use of larger 200b or 240k discs...early 200b discs are 253mm, about 10-15mm bigger than stanza ones, but are offset to suit the twinspots everything is a straight bolt in 9592.jpg PIGDOG boofheads with slotted 240k discs 9585.jpg

'universal' type coilovers for a Civic donated the springs

200b and stanza are solid discs.

CA18DET Wagon is go i took an r31 strut, and cut the spring perch off (the diameter of the spring is far too big to fit up the 1200 strut tower) and while i was at it chopped out about 2 inches from the actual length of the strut to accommodate some koni yellow shocks which i picked up cheap and had rebuilt (which is also cheap to have done). so the front end stiffness is adjustable with a little knob. because i had them rebuilt, i asked for the soft setting to have a hard rebound for goodweight transfer when i go to the drags. the springs are just some pedders lowered made for a stanza which i modified. it is just running the standard r31 vented disk and caliper. both of which are huge for a 1200.

you can also equalise the track by fitting a BW KE30 corolla diff, which is 30mm wider than the 1200 diff. then you have a car with 30mm wider track - back AND front - for better handling again! get the handbrake handle and cable too if you do this.

Rear Disc Brakes

The stock rear brakes are fairly good, a large (for such a light car) 8" x 1.75 brake shoe. Make sure the brakes and clean and adjusted correctly. Using a performance pad will improve it.

But for coolness sake... read the article Rear Disc Brakes.

Datsun 1000

Gary Hamilton managed to squeeze RX7 4-spots on his 1000 sport sedan which uses 13" wheels, but don't ask me how! Gary Hamiltons 1000 Coupe
