Rear brakes locking up

Rear brakes locking up
Hey all.
I've searched and searched for this and found nothing.
Oddly enough, I remember reading about it somewhere and cannot find it.
When it's cold out, and I mean COLD like freezing weather, I go out and start up my 02 FX4 5 speed, then pull forward and the first few times I hit the brakes, I can feel the rear brakes completely lock up at the slightest touch of the pedal.
After I drive a few miles, completely normal operation.
Am I crazy or is this documented already?
Thanks,
RJ

I think this is a common problem with Fords. We had a company pick up years ago that was a 93 F150 and it would do this all the time. The very first time you'd drive it after sitting it would just about throw you through the window with the slightest touch of the brake pedal. Its a very common problem on Fords, and there wasn't any real clear cut solution that I've read of. My Ranger even did it a time or two. I'm hoping that my F150 with 4 wheel discs will never do it.

Wow holy cripes. I didn't expect to see so many replies.
Yeah I'm using cheapo OEM Advance Auto shoes, original drum, and OEM springs/hardware.
Brake fluid is Wearever Gold.
I do, however, use my Ebrake every time I park.
I really don't want to do another brake overhaul so soon after the one I just did last summer.
If I have time, and that's a BIG if, I'll put in that Dot 6 stuff that cheese man is referring to.
Thanks for the all the suggestions guys.

Keep in mind if you want to switch to DOT 5 or other silicone based brake fluid, that you must COMPLETELY flush out your entire brake system. You cannot mix DOT 3/4 mineral-based fluid with silicone based DOT 5.
I just use whatever brand DOT 3 brake fluid I get my hands on, I don't worry about it. I flush the brake fluid every 4-5 years or so.

my truck does this but its usually moisture inside the drums.. or mud... or lil rock chips.... or any dirt inside the drum. if very cold weather probably it retains moisture or "ice" and thats what makes the drum to lock just as it happens to me with mud.. although i have to clean them u just need to get them warm :S
do a disc brake upgrade on the rear and ull be fine and with a 10x better breaks

Funny, I always thought it was cold fluid, thickening in the cold temps and the rear cylinder reacting faster to thick fluid than the front discs, learn something new all the time…
Things to do list:
1) All the other stuff
2) Replace Brakes
3) Some more of the other stuff
Thks for the info.

Its not a specific fluid issue. its like a cylinder/ fluid type thing. whenever they get wet, or moisture gets in them (especially stock) they lock up. Change over your cylinders and shoes and it will go away.
Mine used to do it all the time untill i changed everything. the only time they've locked up after that was when i had it sunk to the back axle in mud (combo of rain/melting snow/ sitting out back for a few days) mud got all inside there and made it a hassle to move.
