recurring brake rotor problem...

[s1ngletracker]

So I've been having a rather frustrating problem with my rotors causing brake pedal vibration. About 3 weeks ago I got brand new Napa premium rotors, and i'm already getting pulsation. Extremely frustrating.

I'm wondering if there's something about my install/bed in procedure that's causing it... or if I'm just having bad luck.

First question, do I absolutely need to get new pads every time I get new rotors? Or can new rotors be used with older pads with plenty of life left in them?

My process for installing new rotors:
1. clean new rotors with brake cleaner
2. Unbolt caliper and remove old rotor
3. wire brush axle flange/hub mounting surface to make sure its clean
4. Take pads off caliper, lubricate caliper slider and where the pad contacts the caliper (not sure what this channel thing is called)
5. Install rotor and caliper
6. Wire brush mounting flange of the wheel to make sure it is clean and free of debris
7. Install wheel and torque evenly to 85 ft lbs
8. Bed in brake pads to rotors using a 10-12 'firm' stops, increasing in speed, never coming to a complete stop.

Am I doing something terribly wrong? Am I missing something? I'm getting really frustrated with having to buy new rotors, and I hate brake pedal pulsation.

Kracka, Mustgofaster, I'm sure you guys have some insight on this.
