Should I replace rotors in pairs?

Yes, always replace brake rotors in axle pairs (both front or both rear) to ensure balanced braking performance. Uneven rotors cause pulling and uneven pad wear.

Do I need new brake pads with new rotors?

Highly recommended. Old pads have worn to match your old rotors. New pads with new rotors ensure optimal contact and stopping power.
