Little brake squeak at full stop on new rear pads/rotors

You know how when you come to a complete stop, at the last moment, the car actually lurches backwards?

So the car stops all its forward motion and then sets back a little. I'm sure y'all know what I mean.

I just replaced rear brake pads and rotors and noticed when I come to a complete stop and the car lurches back when it stops, there is a little squeak. It sounds like something is moving around back there. Here's my theory:

The old rotors were pretty stuck on the hubs...so they didn't move. There's a little wiggle room between the rotors and the wheel studs. When the vehicle stops and changes directions, the rotors move and make a noise. I ran this by my mechanic and he told me when the lug nuts are tightened, it would prevent that movement. Sooooo.....I do not know.

Any ideas out there?

I'm going to pull it apart this weekend and take a look (now that I have the manual...thank you M.L.) and torque everything to spec and make sure the piston is oriented correctly.

 

The noise is only for a split second as the car settles back upon coming to a complete stop.

 

Did all that

 

They're not really squeaking. It's like a thunk after all forward motion of the car stops and the car sets back when coming to a complete stop. It only happens on full stops. It the car does not come to a full stop, there's no noise. It's like a clunk, but a higher pitched clunk

 

I'll try that.

 

Thank you...I could not remember if it made the noise before the brake job.

 

Mine won't shift into neutral while in motion. In order to get into neutral, I have to shift toward reverse. I'm not going to do that when the car is iin motion. It's not a simple slide of the selector to the N spot.

 

Well after about two weeks, the clunk went away. My theory is that after a few weeks, the rotors get "glued" to the hubs. My mechanic disagrees and says torquing the lugs locks the rotors. Oh well, the noise is gone.
