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
See:
* S13 Brakes for smaller, heavy vented brakes
* 258mm Brake Upgrade for large but light solid brakes
vented_brake_rotors.jpg

Notes:

  • Large or wide tires will improve brake contact patch and so are a huge part of increased braking performance
  • A dual Brake 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 Proportioning). For mismatched brakes, or for varying loads, a brake proportioning valve can be fitted 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. 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).

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 B110

You can keep the lightweight B110 struts and improve the brakes.

NOTE: early B210 1973-1975 use the same struts as B110.

Late Datsun 1200 B120 & B210 1976-up are the same but the spindle & hub use smaller bearings

258mm Brake Upgrade

these brakes will stop a car doing 150mph + in the 1/4

POST ** Big Brakes for Big Boys...

For the Imperially challenged, that's a stop from 240km/h in the 0.4km drag race

Better Brakes for HB210

HB210 is the A14-powered North America B210 with 2" strut/hub assembly (same as PB210 Japan).

See Aerospace Brake Kit for A14-powered B210 struts on Ratsun.net. This kit is a version of the B110 Aerospace Brake Kit (see above).

Brake Sizing

Do you need a different size master cylinder? Or a brake booster?

See main article: Brake Sizing

Better Brakes for B310 and A10

Large 268 mm disc brake rotors can be adapted to B310 (Sunny/210) or A10 (Stanza/510) struts - and still fit over 13" wheels.

S30 (240Z/260Z/280Z) Brake Upgrade

In early 1200 racing, Datsun Competition recommended fitting the S30 brakes to the 1200, however it took a lot of fabrication and there are better choices available today.

See Datsun 1200 Competition Suspension Manual

S13/280ZX Brake Upgrade

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

See main article: 258mm Brake Upgrade

BMW E30 Brakes

Bolt E30 vented disc rotors to your 1200 struts. Minimal machining required.

See main article: E30 Brakes

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. .

See main article: S13 Brakes

Better Brakes for Z/ZX Struts

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

Volvo 4-piston Calipers

Volvo 4 piston calipers from a 240DL wagon bolt to the A10/810/B310 strut fine, but have different style flare fittings. Use 245mm B310 rotors (non-vented) or possibly S13 250mm vented discs.

There are several kinds of Volvo 4pot calipers (not all Volvo 4-pistons calipers will fit)

  • Front caliper 38 mm bores 1976-1993 in Girling, ATE, or Reb versions
  • Volvo 240/242/244/245/264/265
    • 14.3mm solid rotor version (263 mm disc)
    • 22 mm vented rotor version (263 mm disc)
  • Rear caliper

RockAuto.com

Works with stock size B310 245mm rotors
12913.jpgAlbum click to view

250 mm S13 Brakes would probably work with caliper spacers (precision washers) about 5mm.

Subaru Leone vented rotors have been suggested but the 242 mm version are just a tad too small for these calipers.

Larger rotors can be used with an adapter to space the caliper farther from the spindle.

Hilux 4-piston Calipers

Toyoda Hi-lux and Landcruisers come with 4-piston calipers (Sumitomo S12). Can be fitted over a variety of rotors.

Nissan Alloy Twin-Piston Caliper

See R32 Brakes#Nissan Alloy Twin-Piston Caliper

Lightweight twin spot calipers from R32/R34 Skyline rear caliper for either 1000 or 1200 race front brake conversion. The rotors it uses are perhaps the lightest 297mm rotor around.

Commodore Caliper

GM Holden Commodore/Calais has a popular caliper for swaps, as it is the same bolt-pattern as the larger Datsun strut caliper and is large yet made of light alloy.

Datsun 810

810 rotors are solid discs. Vented discs like the 280ZX swap are superior for fade-resistant, which is important for racing and for mountain driving.

See main article: 810 Brakes

Datsun 910

Datsun model series 910 was produced 1979-1986. In some countries it was marketed as "Bluebird". In the United States it was badged as "810" or "Maxima".

Nissan B13

Nissan Sunny/Sentra B13 (1990-1993) SR20DE - swap is same as 257mm S13 Brakes except that B13 uses:

  • 4x100 PCD, so the rotors need to be redrilled for 4x113 PCD.
  • height is 4mm different, so different caliper adapter plate is needed
  • Can use the B13 calipers per below photos
  • see swap details at S13 Brakes

feral's vented package using modified 240K twin-spot calipers. http://www.datrats.com.au/BRAKES.html

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.
