Last time I replaced my front pads, I did not replace the rotors. I'm not sure if this is the reason for my loud ass brakes, but I still have alot of life left on the pads. Can I cut the rotors or replace them without changing the pads?

I have a similar problem wher mine scream for the first three or application in the parking lot. After that they are fine until six hours later. I replaced the front and that is where the noise is coming from with rotors from autozone because I chipped my OEM when removing to have them turned. On a Sunday it wasn't possible to get rotors other than this location. I can't determine if my noise comes from the pads or rotor. My guess is the rotor since I have the same pads on the rear OEM rotors and no noise. You could also have the sensor touching and causing the noise. There is a DIY on the forum to correct the issue. I believe its just a matter of filing a chamfer on the edge or so.

I doubt it would be the sensor at this point. I replaced the brakes probably last year some time, and it just started squealing a month ago, which prompted me to inspect the pads to see if they needed to be replaced.... but they do not.

molycoat or lube them, noise is a high pitch vibration

what type of pads?
try scuffing up the rotors with sandpaper, and lube all pins and contacts. apply anti-squeel paste to back side of pads.

hawks. I do notice the rotors have a little lip on them. Think the squeal is coming from the back side of the pads where they come in contact with the pistons, or from the pad / rotors?

Also, scuff the rotors??? Or the pads?

Mine squeak too! It's annoying and down right embarrassing on occasion. iDrive tells me I have 9000 miles up front and 13000 miles in the rear before replacing. There is a slight lip on the outside edge of the rotors though. I'm wondering if this is the culprit or not. Do they make any spray for this? My apologies if it seems like I hijacked this thread.

I installed new Hawk HPS pads 2.5 years ago. About 1.5 months ago they started squealing at low speeds. (Usually stop and go parking lot speeds). There's still a lot of meat on the pads so all I did was to re-bed them again. Go 40 mph (or as fast as you safely can on the street), then slow hard to 10 mph without stopping and keep doing that until the squealing is gone. It's been about 3 weeks now and still no squeal.

To stop your brake squeal:

You need to apply Brake Pad Paste to the BACK of the brake pad where it makes contact with the shoe.

To do this you need to REMOVE the pads, clean out the shoe, clean the back of the pads and apply the paste to the BACK of the pad (on the metal plate), refit the pads and test drive with some firm braking.

As "HealthServices" said in an earlier post, the brake squeal is actually the vibration of the brake within the shoe. It is not the rotor.

may as well sand them both, just to break the glazed surface down a bit. just do it by hand real quick. no need to get crazy sanding.
