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.<hr></blockquote> | ||

This article focuses on advanced brakes, requiring machining.
For general brake improvements, see Brake Swaps

Front Brakes
Using Z-car or 280ZX struts
Z means 240Z, 260Z or 280Z (Nissan chassis code S30). The 280ZX (S130) came later.
See 280ZX Strut Swap for details. This section will focus on even better brake choices, after you've got the Z or ZX struts.
Rotor Comparo
- 240/260/280Z: 272 mm (10.7") non-ventilated
- 280ZX rotors: 254 mm (10.0") ventilated, 18 mm thick, fit Z-car struts
- 300ZX rotors: 274 mm (10.8") ventilated, 22 mm thick, don't fit 280ZX struts
All the Z and ZX 4-bolt hubs will allow interchange of any rotor onto any hub as far as being able to be physically bolted together. In other words, any Z or ZX 4-bolt hub will accept any other Z or ZX brake rotor as far as physically bolting them together. However the rotor thickness and offset are more important. Also any Z or ZX 4 bolt hub will also fit onto the Z spindle too, with the only difference being a very slight displacement of inside seal (the wheel bearings are the same).
300ZX calipers are wider, heavier, and had a different bolt spacing than did the 280ZX or Z calipers, even though the piston and pad area on these calipers was no bigger than the piston and pad area on the 280ZX caliper.
Apparently the stock non-ventilated rotor is close to overheating on a 2800 pound Z-car, but may be fine on a light 1200.
It seems the 280ZX strut lets you use a 1" smaller wheel?
Adventurous swapsters: notice that 1981 Toyota Cressida caliper bolts to the Z-car strut and has slightly smaller piston and pads. What size rotor does the Cressida have?
Ventilated 300ZX Rotor on Z Strut
Use 280ZX caliper. as 300ZX calipers don't bolt on, having the bolt spacing farther apart.
- The caliper has the bolt threads. So drill out the Z-car strut to fit them and put bolts through the strut holes into the caliper
- Use a spacer on the caliper bolts to center the caliper over the rotor. Use early 240Z hubs. A thick .160" washer, is placed between the caliper and the strut. If using newer hubs, which are thicker, it won't be a bolt on, but probably you'd have to machine the hub.
- Machine the larger 300ZX rotor down to reduce diamter by about 1/4 inch (it should just come past the brake pads)

MK63 Racing Brakes
Fits Z-car Struts and B310 large (13" wheel) struts. See Strut Swaps.
These were the FIA brake calipers, offered in the Nissan 'Sports Option' parts lists in Japan, and through Datsun Competition in the USA. They were fitted to most of the works 240Z and 260Z rally cars, most of the works circuit racing 432R and 240ZR race cars, as well as many of Skyline, Sunny and Violet race cars.
- Approximately 50% more pad area than stock 240Z brakes
- Require removal of the backing plate. Complete bolt-on.
- Feral used 261 mm diameter or even 253 mm rotors.
- early S110 rear discs and calipers were small and very light and fit under 13's. The discs were same as R31 skyline...discs and calipers came on an E-PS110 Z20E powered with FS5w71B & HB 38
rear axle. It had an SX badge on the rear hatch.
Nismo MK63 Sumitomo 4 pot calipers
- 89.9 bolt spacing
- Has four 41.3 mm pistons
- Caliper repair kit 41120-68225 fixes all seals for one caliper
- Replacement piston 41124-68200
MK63 Solid Rotor
For stock 240Z solid rotor, and stock 240Z strut. Available from Courtesy Nissan $700 USD

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.
