parking brake probs....

I did a search and what I came up with was moisture gets in brake line and freezes the brake in place, thus sticking the parking brake. Solution: replace brake cabel.

my question:
How dose replacing the cable fix the probiblem? couldnt moisture still get into the cabe and freez? I would also like to know if there are any other solutions to this probiblem (such as seals). Or if there is even a way to manualy release brake (hopefully without jacking up car). Or mabie its hopeless and I just need to park on flat land when its freezing out. and by the way its geting down to about 20 degrees at night right now.

Moisture gets into the cable due to broken seals. This is normal if you still have the original cable on there. The solution is to install new cables with unbroken seals.
You can leave your car in gear instead of putting it on the e-brake to prevent such problems for now.

I always put the car in gear, but there are a few times where I leave it idling while I'm getting the mail or scraping the car off while it warms, thus the use of a parking brake. Never rely solely on the parking brake when you're not going to be right with the car on an incline. For those who argue about a turbo timer used with the parking brake... if you're on an incline, wait it out and then put it in gear as well as using the brake.

New cables will really fix that? I always thought it was something else that froze.

but isnt it hard on the tranny if you just use 1st gear to park? I know with auto trans it uses first when in the parking position and eventually wares out the gear if you dont use hand brake also...

No, it's the cables. This happens more often if you don't have the plastic shields bolted to the bottom of your car. If you don't, make sure you bolt them back on there after changing the cables or you'll have to change them again soon.

Dump the OEM cables and make your own.
I use nylon coated wire rope and some swedges. Takes about 30 minutes and works great. Since there is no inner/outer cable, theres no chance of corrosion or freezing.

Cables fix the problem if it's the cables freezing. If it's a hung caliper or stuck slider, the cable isn't going to do a thing--totally separate entity.

Putting the car in gear isn't hurting the car unless someone rams you or drags the car away in gear. It's simply using the drivetrain's resistance to move and compress air to hold the car. If you're parked on a hill, put it in gear, press against the curb if possible with the wheel turned appropriately, pump the brake, and set the handbrake. I don't think the car will decide to desert you.

parking brake cables

I have shaved the jackets off of several cables so far, using penetrating oil and grease, and saved all but one, they work great...I like the suggestion of using the nylon coated cable and swedges which I'll try next.

When putting the vehicle in gear to stop it from moving, you're simply using the engine's compression to hold it as far as I know. And with auto trannies, Park is the same as Neutral, except I think there's a pin that engages inside and holds the vehicle in place

The first time my cables froze, I burnt out my clutch in my driveway thinking that my snow chains were frozen to the ice. When I figured out the problem, I made an adapter to blow WD40 through the cables using my air compressor. That only worked untill the next freezing rain. You just have to buy new cables every ten years. Bob('85 since new)

ok probibly a dumb question but what are swedges? I agree that it would be a good idea using wire rope seeing that its only about .20 a foot. What diameter of wire do you use? and what about the seals?

Some pics would realy help, I havent dug into anything yet because its about 35 degrees outside with winds so I dont want to get under there unless I have something to replace it with. Oh and by the way, my brake came off when it got above freezing.

Here is a link to a pic of a swedge. Basically, you feed the wire rope thru it and flatten the swedge to hold the cable in place.

When I made a set of cables for my 86, I threaded the wire rope through the stock eyelets, so it wouldn't hang down then I cut the eyelets off the ends of the OEM cables(where they pin to the caliper lever) and swedged them to the wire rope. To connect the wire rope to the front adjuster, I looped the cables around the adjuster ends and swedged it in place.

So you swedged the original caliper end of the cable

to the new cable? Interesting, how did you get the old cable residue out of the cable end, so you could swedge it on?
Looping the cable around the adjuster "rocker" and swedging it is a good example of Keep It Simple engineering.
