Crazy brake judder after sitting in rain for a two days?

Torque on a lug nut cannot be measured accurately when loosening. The initial break-away loosening torque is ALWAYS larger than when tightening. I seriously doubt that your dealership had overtightened the lug nuts.

I checked the torque as if tightening the lugs, not while loosening. Started at 90 ft lbs and increased by 10 ft lbs until it didn't click immediately. Tested with two different snap on wrenches to verify. I would never use a torque to remove lugs. So yes, the dealership did indeed overtorque lugs. Not surprising since every shop I've ever been to does it too.

So, problem is back just as bad as before. After cleaning up the rotors and rebedding all was good for about 3 days. This is what both of my rears look like now!

Again, these rotors/pads have less than 1000 miles on them. Stoptech all around but the fronts aren't quite as bad as the rears, but are still unacceptable IMO.

With the rotors in this condition, can I simply swap the pads with something better or will I be trashing the new pads?

What brands is everyone else using with success for street?
