I heard the some toyota 4x4 brak ecalipers would fit the 280zx. What years and models are these? and do i need just the caliper or the bracket also and do the stock pads fit? and do they work with stock wheels? and if you have any other info on this conversion please fill me in.

 

SEARCH for something like "Toyota" or "4 piston caliper" or "brake upgrade" in the 280zx section ... lots of results.
