The brake rotors on your Acura are important parts that help the system work as a whole. They are metal discs that, along with the brake pads and calipers, get the wheels of your vehicle to stop rotating and come to a stop when you press on the brake pedal. They are attached directly to your wheel hub. When you step on the brake pedal, your brake calipers work to press your brake pads against the rotors. This process causes the wheels to slow down. Friction is generated during this process, which means your rotors, along with other parts of the brake system, wear out over time. Some of the signs of worn brake rotors can include visual score marks or grooves on the surface of the rotors. While rotors are designed to wear down to some extent, they shouldn't be worn down completely as your safety on the road can be compromised. Another sign that your Acura's rotors might need replacement include increased stopping distances or shaky brakes. If you need replacement rotors, it's important to get the best possible ones for your ride, which would be OEM. You can find OEM brake rotors here at Curry Acura Parts.
