Re: disc brake springs
The groove in the piston has a slight slight angle on one side. When the brakes are applied, it make the piston seal deflect slightly. When the brakes are released the seal straightens back up and slightly retracts the piston. Early disc brakes didn't have this feature and they did drag.
