"If an AC motor is operated for long on high load via relay, will the relay start acting funnily when its switched off

Not if the relay is correctly rated.

I doubt that your general question above is of any relevance; this is almost certainly something specific that's happening in your particular set-up.

Don't forget that this is not purely an electrical/electronic system! Have you checked that it's not just a case of the brake getting physically stuck or jammed?

Maybe something is loose, and it moves a bit when the AC motor is under heavy load, and that's enough to make the brake stick?

Maybe something is not rigid enough, and it flexes a bit when the AC motor is under heavy load, and that's enough to make the brake stick?
