OK, I looked at my pads and rotors, the pads have at least 70% of the pad left on them, the rotors are smooth as a babies you know what.

BUT, when I drive, I get a squeal from the wheels. I assumed I needed to change out the pads and possibly rotors but that does not seem to be the case.

Is there a "glaze" on the rotors that is causing this noise. If so, is there a way to clean them? I really don't want to have to get new rotors because the ones on there look pretty good right now.

 

Is it both wheels or just one?

 

SOunds like both wheels.

I went out and bought some disc brake spray to make them a bit quieter.

 

Eliminating Disc Brake Noise

 

Part of the problem has to do with semi metallic pads I think. I've fought the brake squeal on the Expedition for quite some time to no avail.

 

I replace my front pads every 12-18 months when they start to make annoying noise.

 

What pads have you been using?
