All Cavaliers from '94 to '04 use a 3/8 Allen key on calipers.
Check the fluid or posibly the pads are wearing.

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.
belt dont no 80's but the 90's 300ZX are belt driven
Worn belt, brake pads, bad CV joint are a few possibilities.
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.
Unless you have a GSI prizm I am not sure if they were made after 92 you would have brake shoes on the rear, pads in front.I just replaced rear shoes on a 97 and the 94 is the same car.They are hard to replace if you do it yourself pay close attention to how they look before you remove them, they are tricky. Patience is the key to this job.
