Default tips for unsticking a stuck brake

i have a 92 f250. whenever it gets cold and snowy the rear drums freeze. i've always been able to give it a little throttle, dump the clutch and get them to break loose. this morning i couldn't. i did a sideways lap around the block before i gave up and parked in the street infront of my house. i don't think i can get the truck in the driveway. what are some tricks i can try?

once i get the brake loose what can i do to prevent this from happening? what causes this? is the cable frose or is there ice built up in the drum?

2 years ago i put in new drums, shoes, hardware and cables.

i had the brakes stick on my wife's car this winter. i sprayed windshield deicer in the caliper of the rear wheels. i don't rememeber the brand but it is in hand spray bottle it has also opened up some padlocks that were frozen shut. i have no idea if it will hurt anything on your brakes but it did not seem to hurt ours

usually if i have the problem its in the cable line. i spray wd-40 into the line, and then after some time to let things dry a little i take some heavy sticky grease and pack the end of the lines with it to keep water and crap out. im sure theres a right way, but this has worked for me

also make sure everything is well coated with break grease, and think about replacing the pistons, i think they cost around 30 for the pair

You said you changed brake hardware 2 years ago. Did the problem exist before then? If not, you may want to re-check your work. Something may be mis-installed. Good luck.

Popping the clutch on frozen brakes is a good way to break something.

If the brakes are frozen, use a weed burner to heat up the drums.

Also, in wet weather around freezing, don't use the parking brake. Leave it in first and chock the wheels.

To prevent wet brakes from freezing, drag the brakes slightly before parking to dry them. Or as AP said, check the wheels instead of using them.

Yes, I come to a rolling stop when parking drums, I have had this happen on Fords. This is a side note but I almost always remove the drums at service when rotating tires. I take hand grinder and take the ridge out of them, makes it super easy to check hardware, make sure adjusters are working, etc. Wheel cyls are cheap these days, a 92 would have been on at least a second set.

Are you sure they are freezing, or are the shoes and the drums rusting together?? This seems to be a common problem lately, caused by a combination of the higher metallic composition of non-asbestos pads and the instant rusting that the chicom rotors and drums seem to be prone to. I've seen and heard several complaints on this.
I installed new pads and rotors on my crap-box '94 Jetta las fall, ever since the rear brakes howl for the first few feet after being parked overnight or in damp conditions.
Looked at it a couple times, all appears to be fine except for the insta-rust that forms overnight.
