hoping someone can tell me whats gotta come off to remove the rear caliper off a 93 z28, i cant seem to remove the parking cable bracket

 

The wheel, then it's just 2 bolts to remove the caliper from the rotor.

Removing the caliper completely; just pull/angle the end of the cable off the arm, compress the sleeve tabs in the bracket to remove the cable from the bracket; then pull the banjo-bolt from the line.
