Without knowing what piston return spring you are talking about it will be hard to come up with a diagnosis for you. If you are talking about the rear brake return spring then you may have to have the rear brakes inspected to see what has come apart or is binding in the brakes. Have a mechanic like one from YourMechanic inspect the brakes and diagnose the problem before a fix can be done.
