I cheaped out and bought napa ceramic pads to put on my 13 for temporary purposes and they did the same thing, and only when hot. I ordered a set of semi metallic oem pads and all noise went away.

Ya, I was afraid that might be the answer. Did you buy motorcraft from Ford?

Try some disc brake quiet between the back of the brake pad and shim, (obviously that is if the shims are not riveted to the back of the pad, quality brake pads usually come with riveted shims to avoid vibration squeal). The vibration between the back of the pad and shim create an annoying squeak. It usually is either a red or blue compound that you can purchase from any auto supply house.

I put some red grease between the back pads and the caliber.

Red grease, and brake quiet are two different things. Sounds like you need to either live with the noise, do them again using the right stuff.

Some combinations of brake pads/rotors work better than other.

Even though you had the rotors turned, the fact the squealing started a few weeks after the work means something has changed in that time.

Are the rotor surfaces shiny like silver looking or do they have blue streaks in areas? Look at the pads themselves, they should have even wear and a very low matte finish (not shiny).

I found that the FOMOCO pads for me don't work well (Squeal) no matter what rotors I use, what break-in procedure I use, or how I drive. I switched to ceramics with OEM rotors (and have also tried aftermarket ones) and have never had any squeal issues. This experience is on both our Escape and my Mustang.

As JZ pointed out, anti-squeal and grease are not interchangeable. The back of the pad should get anti-squeal and the contact points or slides on the calipers get grease. Grease over time would simply be squished out if you used it on the back of the pad. Anti-squeal gets rubbery after a few mintues, the grease stays like...grease.

Well when I say red grease its because it looked like it. I was at an automotive bay where the mechanics teach and let you do it yourself. For $6 an hour, I can't beat that. They gave me two kinds of "lubricant". One came in little packets that was used for the pads where they slide back back and forth in the piece that holds them (I don't know what it is called), and was greenish. And the red stuff was in cup with a brush and they told me to smear it on the back of the pads so there wouldn't be any friction causing noise when I use the breaks.

So this spray only goes on the back of the pads? I don't understand how that will help with the squealing. Doesn't the squeal come from the pad rubbing the rotor when in use?

The squeal can be from two main sources, pad to caliper contact or pad to rotor contact.

If it's pad to rotor, it won't matter what you put on the back of the pad (pad to caliper).

Pad to rotor noise is frustrating as hell and can get expensive to resolve (new pad/rotor combinations).

I use Akebono ceramics and have never had any issues with OEM or aftermarket rotors. You can find them on R o c k auto . c o m
