The pads grip these discs when you press the brake pedal to generate friction between the rotors and the friction surface on the pads. Your 2013 Scion tC brake rotor provides a surface for your pads to grip and bring you to a stop, so your braking system is only as good as the brake discs. When it's time for new ones, AutoZone is your one stop shop for 2013 tC brake rotors. We offer free next day delivery or same day pick up at a store near you when you shop online.
