I have had NAPA slotted and drilled rotors and Bendix ceramic pads on the front of my 1991 S10 Blazer 4x4 for about 2 years and aluminum drum brakes on the rear. I feel the front brakes through my foot and I think the run-out is .008" -.010" . I have not had any braking advantage using slotted and drilled rotors when driving in normal stop and go traffic. The slotted and drilled rotors are designed to vent plasma between the pads and rotors in a high speed stop or during road racing. A street driven vehicle does not need those type rotors.
When I replace the Bendix ceramic pads, I will replace them with Raybestos ceramic pads and Raybestos standard rotors and toss the vented and slotted rotors.
