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

Spooler

I use Carbotech XP8's, dusty but none of those issues and yes I do get the rust if the car was parked after a rain or after washing. The lug nuts should have been torqued down to 80ft/lb's. If you use an extension, 85ft/lbs. If they were ran on with an impact, that would cause your issue. You may have to turn them to true them back up. Standing on the brakes at a light with hot brakes can cause issues also.
