Brakes - ZR-1 Net Registry Forums

hi, i bought a brake system off somebody, they told me it was off of a ZR1. its a 13inch rotor, and 2 piston PBR caliper, is this setup from a ZR1? also if it is, i need a little help, the calipers have ALOT of play inside of the brackets maybe an 1/8 inch, movement of the caliper is on the same plane as the rotor, no problem between the pad and rotor. they work fine, stops MUCH better than my stock LT1 trans am brakes, but clatter like hell over bumps or rough asphalt. no noise when even the slightest amount of brake pedal pressure is applied. i looked at a 80s vette, it had the same calipers but with a smaller rotor, i didnt notice any parts that i was missing, but the caliper was snug. Anyone have anyclue? or even have anyclue as to what im trying to explain? also is there a somewhat bargain upgrade for calipers?
