Old schwinn having problems with rear brakes.

I just bought a used Schwinn Caliente and everything seems to work great except the back brakes make a loud screeching noise and wobble. The angle of the brake pads look right and the rim was wiped down with rubbing alcohol to remove build-up. If anyone has anymore suggestions I open to almost anything.

Welcome to BF. I have some suggestions:

1) Ensure brake caliper mtng bolt is secure
2) Toe-in brakes 1 mm in direction of rotation
3) Brake pads may be old, dry and hard and will squeal no matter what. Sand brake pads FLAT to remove surface hardening or Replace brake pads.
4) Check vertical adj. of brakes to ensure pads are not touching tire.
5) Check trueness of wheel. Although an untrue wheel will not cause a screeching sound, it may cause an on-off effect which could be interpreted as a "wobble".
6) Ensure rear wheel hub is not loose. ( Wobble issue ) Adjust as needed.

P.S. Just as part of a good maint. protocol, use a dry lube/silicone-based lube to lubricate brake pivots, being careful to avoid dousing brake pads and rims.

Get a good maintenance/repair manual such as "Zinn and the ART of Road Bike Maintenance". Check out Parktools.com website for repair/maint. info. Also bicycling.com.
Good luck with your new USED bike. Happy Wrenchin'!!!
