Breakes. Hard Pedal. Rear breaks do nothing. on 1990 Jaguar XJ6

The break pedal is extremely hard, and upon inspection of wheels, I discovered the rear breaks are not working at all: rust has accumulated and the disks and wheels remain cold. I am clueless as how to proceed to repair my car's break system.
