I was getting some serious squeaking from the rear passenger brakes on light braking only when the pads/rotors were cold. I figured it was the squealers and that I needed new rear pads even tho the outside pad seemed to have a little life left. So, I replaced the pads with OEM but didn't touch the rotors. I used the correct shims and PLENTY of grease.

The noise was still there, loud as ever. I thought possibly coincidence and the pads needed to de-glaze or something. Well it's been two weeks, several hundred miles, and the squeak is still there, loud as ever, under light braking with cold pads/rotors.

No clue what it could be. suggestions? Car has 108k on the odo.

 

Are you still on the original rear rotors? Measure the thickness of it, if it's under minimum thickness that might cause the brakes to squeak.

 

Yes orig rear rotors.. Didn't have them turned or anything. I'll try to check it out but I doubt I have the equipment to do it accurately

 

Both sides squeek?
Do the rotors get warm without braking?
Do they get equally warm after braking?
The e-brake works on both wheels?
Any deep grooves on the rotors? (check both sides of the rotor)
You did line-up the groove in the piston with the pin on the pad..? (yeah you did)
Did the piston turn easlily?
How were the old pads worn, straight, etc?
Did you actually reach the wear indicator, did it touch the rotor?

Thats all I can think of right now.
