The R1 Concepts slotted black brake rotor for 1977–1993 Chevrolet K30 (front left) is a slotted front-left rotor sized for that truck application. The slot pattern assists in maintaining pad contact and in venting debris and gases from the brake interface, delivering an application-specific rotor intended to restore the front-left braking surface.
