What type of front brakes do I have on my 1985 Turbo Z?

[DCTZ]

Are these ATE or Kelsey-Hayes? I need new pads and rotors.

If they are Kelsey-Hayes, there should be a KH cast into them somewhere, at least in my experience. I do know that mine had KH calipers, and those do not look like what I remember. Of course it's been nearly eight years since I saw my factory calipers . . .

Those are ATE. The ATE caliper uses that large spring, the K-H does not. I also believe the K-H calipers from that era allowed the rotor to come off without taking off the caliper adapter.
