2007 Mercury Milan emergency brake squeek

[48bill]

I know this is not a hot rod but I have found excellent advice here.
My wifes 2007 Mercury Milan with 105,000 miles has developed an annoying, to her, squeek first thing in the morning when the car sat overnight after the brake is released and she applies the brakes while backing out of the driveway. It only occurs first thing in the am.
I have tried PB Blaster which stopped it for a couple of days but it is back again.  The cable is mostly shielded so I can't really get a lot of lube on it.  This am she said the noise was there and she had not set the emergency brake ove night.
Any suggestions.  Thanks.

If that is like my son's 06 mustang, the cable is almost froze. The e brake has a rotator on the piston that forces it in. If the cable won't retract, the piston has some pressure on it. I had to rebuild a caliper because of this. The cable let moisture in. I replaced the cable and that fixed it. I might add this is a known issue on that era of Ford products.
