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.

Hi there my son is a mechanic and scanned it with his snap on scanner it said there was an open circuit so I checked all the wiring up two the loom and everything was fine I was thinking it could be a relay ?

Could be a relay, also check continuity of the wiring if you can trace back.
