This started after I did the front brakes. I replaced them with top of the line quality ceramics. I cant remember now if they were Weaver, Raybestos or Advance auto Gold , I have used each in the last few years on vehicles. I had a local shop turn the rotors, I used brake parts grease on parts and pad backs, there were anti rattle/squeal (whatever you want to call them) shims already installed on the pads. Just after I test drove it I got a noise that would sound like "week..week..week" that was cyclical with the tire rotation, and inside and outside it sounded like a small squeak. I checked the clips on the caliper and the pins several times and regreased the pins. NO difference. It goes away if you apply pressure to the brakes and the pads close on the rotor. so its like something is out of balance/round and as it passes it hits the pads and makes the noise.
It got really bad, just a bit louder than it was. I pulled the rotor had it returned and that got rid of the noise, I figured it was off a but in the lathe the first time and was turned slightly out of round. Well after a week and a half or so and not more than a few hundred miles the noise has returned!!!
At this point I am not sure if uneven pad wear could cause it,,but why after a week of NO noise would it come back, the pads are way softer than rotors so they should of worn down if this was an issue I would think? Can a bad hub do this? But if the hub was bad (no movement on tire when jacked up) wouldn't it not matter if the rotor was returned and it got rid of it? OR my last and only thought at this point is the whole rotor is warped down to mounting surface and when it was returned the brake surface was true but at time increased that surface got worn back to the amount to allow the pads to be hitting when no pressure is applied to make the sound audible again?
Its not hurting anything, just drives me crazy cause I want it right and it makes the car sound like a piece of junk.
