So I jacked the rear of my car up, and I'm not sure what to do. Have changed plenty of front pads before, never rear. I'm used to unscrewing a caliper retaining bolt, sliding the caliper up, replacing the pads, slide caliper back into place, tighten bolt, done. The rear caliper assembly looks totally different . I checked shbox.com and there is no write up for this procedure. Can someone tell me how to change my rear brake pads? Thanks!!

 

This is from Alldata,an online manual.It's for a 94 Z28 but I think it's all the same thru 97 at least.
Hope it helps.

REMOVAL

1. Remove 2/3 of the total brake fluid capacity from master cylinder reservoir.
2. Raise and support vehicle, then remove tire and wheel assembly.
3. Install two wheel retaining nuts to retain rotor in position.
4. Position one end of a suitable C-clamp against inlet fitting bolt, and the other end against outboard shoe and lining, then tighten clamp as shown, Fig. 2, until piston fully bottoms in caliper bore.
5. Remove upper guide pin bolt and discard.
6. Loosen lower guide pin bolt, then pivot caliper downward on lower guide pin bolt to expose shoe & lining assemblies. Use care to avoid damaging brake hose.
7. Remove shoes and linings from mounting bracket.

INSTALLATION

1. Install outboard shoe and lining onto mounting bracket, ensuring insulator on shoe is positioned toward caliper housing.
2. Install inboard shoe and lining. Ensure wear sensor is positioned nearest caliper piston. When properly installed, sensor should be in trailing position when wheel is rotated in forward direction.
3. Pivot caliper into position over shoes and linings. Ensure springs on outboard shoe do not protrude through inspection hole in housing. If protrusion is evident, lift caliper housing and readjust position of outboard shoe and lining.
4. Install new upper guide pin bolt and torque to 26 ft. lbs., then torque lower bolt to 16 ft. lbs.
5. Fill master cylinder to proper level, then pump brake pedal firmly and slowly three times to bring pads into contact with brake rotor.

 

Thanks! Got it done, but discovered a bad caliper on the driver's side and pads worn so low on the passenger side that the rotor was warped. Fixed all, installed new pads, and now my ABS light is off.
