I am slightly worried about how loose the brakes feel when I drive.
Hi. If by loose you mean a low pedal, you might have a hydraulic leak. The hydraulic system on your brakes is a sealed system. If you develop a leak, the pedal can go to the floor. Leaks can be internal, like in a master cylinder or external, like on a hose or caliper. Because of the safety factor, I suggest getting the brake system inspected by a qualified mechanic, such as one from YourMechanic.
