What’s the fault, what are the symptoms, is this an in-dash error. I take it you haven’t had the car scanned for fault codes? Manual or auto?
 

The electronic parking brake is normally pretty robust. Rear calipers are known to seize, especially at this age, but you’ve already swapped it out. Are you getting 12v to the module? A cheap multi-meter is invaluable. Also check wiring there, especially the ABS wiring.
