While a vehicle's performance is often what reviews will focus on, you have to talk about a vehicle's brakes. While brakes might seem simple as a concept, in execution, they're comprised of a complicated system. In order to make sure your vehicle is able to slow down effectively, all parts need to work coherently.
When you press down on your brake pedal, it releases brake fluid to your calipers. In turn, the calipers activate your brake pads, which squeeze down on the vehicle's rotors to apply friction and slow your vehicle down. If any part of this system fails to work as intended, then you're vehicle might not stop when you want it to.
There are a number of signs that might mean your vehicle's brakes need repair. Anew noise you hear when they're applied or any stiffness or stuttering can mean something is wrong. Make sure you're getting your brakes looked at routinely by your mechanic or dealership.
