Cadillac Repair: brake problem 1987 Cadillac deVille, cadillac deville, brake components

Question
My son recently received his grandmother's 1987 Cadillac with only ~49K miles. The rear passenger side wheel has locked up after the car sits in the driveway overnight. I suspect a brake problem. The brake light doesn't come on. The wheel moves in reverse, but not in drive. The other wheels appear to be fine.

Answer
Pull the tire OFF and inspect the brake components.
