High performance brakes are made of different compounds that are more resistant to brake fade during heavy usage. Those different compounds lead to a squeal or screech sometimes.

Regular road brakes typically only squeal/screech when their wear indicators are rubbing against the brake rotor, letting you know it’s time to replace them.
