Z32 Front Brake Swap

You can increase the stopping power of your front brakes by using the front rotors and calipers from the later 1990-1996 300zx.

Tools Needed

  • Jack
  • Jackstands
  • Line Wrench
  • Ratchet
  • 17mm Socket
  • Cutoff wheel or Hacksaw
  • Punch
  • Hammer
  • Breaker Bar
  • 30mm Axle nut socket

Parts used for install

  • 1987 - 1989 Turbo front Hubs
  • 1990 - 280mm x 26mm Front rotors
  • 0.170" Spacer


Z32 Caliper Information

The Following is some information on what year Z32 came with what Calipers. This way you know what you are getting.
  • The "26mm Aluminum" calipers were used ONLY on 1990 non-turbos. They used a 280mm x 26mm rotor.
  • The "30mm Aluminum" calipers were used on 1990 Twin-turbos and ALL 1991-1992.5 300ZX's (both turbo and non-turbo alike). They used a 280mm x 30mm rotor.
  • The "30mm Iron" calipers were used on ALL 1992.5-1996 300ZX's (both turbo and non-turbo alike). They also used the 280mm x 30mm rotor.

Installation

  1. Jack the front of the car up and secure on jackstands.
  2. Remove the front wheels.
  3. Remove brake caliper and line from the car.

  4. On models other than 87+ turbo, Remove the front hub assembly and replace with the 87+ turbo front hub.

  5. The Z32 Caliper is much longer than the Z31 caliper. By Cutting an inch or so off the dust shield the caliper will now fit without rubbing.





  6. Install the Z32 Front Rotor by slipping it on the wheel studs.
  7. Next install the Spacer so the Caliper will be centered.
  8. Now to modify the caliper so the Z31 Brake lines will work.
    1. First separate the two halfs of the caliper.
    2. Then remove the piston in front of the Fluid inlet.

    3. Once piston is removed this is what youll see.

    4. Just take a punch or similar and tap the orifice out from inside out.
    5. I found it nessassary to stick a phillips in the front of the inlet and turn the orifice to "break"it loose.
    6. This is what you are removing.

  9. Install the caliper and bleed the brakes.
  10. Install the wheels and lower the car.


Other Information on this swap

This swap is known to work with the 87-89 turbo and non turbo wheels. At this time it is unknown if the 84-86 stock wheels will work without rubbing the new caliper.
