what is the breaking system for the S60, 2013. Why are my tires making squeal

What is your question?

when i put take off from a stop, the front wheels squeal, when I make a sharp turn the front wheels squeal. When I try stopping suddenly the feeling is as if the front brake pads are skipping over the part that helps the braking system stops. In other words I am afraid that if I have to stop suddenly, the breaking system will not work. properly.
