Talked with Eric the service mangaer at Stead in Walnut Creek, just to echo what some have been saying. I was having the same problem under light braking set up a weird squeal/vibration. He said it is often after rotors get wet, such a washing or in wet conditions. He said just do a couple off ramps 70 to zero as hard as you can 2 to 3 times. Make sure no one behind you and that will solve it untill the next wet soak. Worked for me.

 

not rained here in weeks and I only washed my car 3 weeks ago. I doubt if the wet conditions are the only reason.

 

By golly, I think this is what I said on the first page! Works for me! (I did do the brake break in process when I first got the car for pccb's - don't know if that helped or not).

 

Never even a whimper from mine.
