Normally a bad brake caliper will stick when you apply the pedal and then slowly release. It will make your vehicle feel as if the brakes are applied even when they are not and then slowly they will release. Eventually they will stick and stay stuck. It is worth mentioning that squelling or scratching noises are not neccesarily a bad caliper. Those noises are usually caused by the brake pads themselves either sliding on the caliper or the scratching sound is probably the brake wear indicators letting you know you need new brake pads.
