All Cavaliers from '94 to '04 use a 3/8 Allen key on calipers.
Check the fluid or posibly the pads are wearing.
To change the back brake on a 1994 Chevy Cavalier, first, safely lift the rear of the vehicle and remove the wheel. Next, remove the brake caliper by unbolting it and sliding it off the brake rotor. Take out the old brake pads and replace them with new ones, ensuring to compress the caliper piston if necessary. Finally, reassemble the caliper, reinstall the wheel, and lower the vehicle.

Good question. The caliper will bolt up, but you'll need to get the 300zx rotor redrilled from 5 bolt to 4 (half the holes line up) and you'll need new lines. Don't forget the pads, pins, and retainment clips.
You take it to a mechanic that knows what he/she is doing.
Worn belt, brake pads, bad CV joint are a few possibilities.
belt dont no 80's but the 90's 300ZX are belt driven
You probably have a warped brake rotor. New rotors are fairly inexpensive, I would replace both front rotors and brake pads while your in there. The calipers and sliders along with the brake hoses and lines need to be examined also.
You can gain access to the bulb from the trunk?
Not unless you also change the wheel hub. This might require a complete rebuild of the rear axle.
You'll need to remove the wheel, the brake pads and the caliper. Once all of that is out of the way, there are rotor retaining screws that need to be removed, either on the studs, or on the axle itself.
