When you race with turns stuff bends, as the wheel hub and wheel bearine deflect during cornering, the rotor hat is sandwiched in between and forced to go along for the ride, the caliper is attached to a more rigid suspension component, the upright, when these are not in parallel the deflection of the rotor relative to the brake pads forces them away form eachother, there is not springback in the piston seal to push everything back together, the pads are then pushed off the rotor until the brakes are applied again...
