I used to have this same type of problem in my B3 Passat. The cables for the parking brake get moisture in them and it causes them to hang up. If you could get the car in a garage or you might need to get under the car with a hair dryer or something to get a little bit of heat on the line where it connects into the rear caliper.

If it's not hanging up too much, you might be able to drive the car around and that will cause some heat build up. NOT recommended, but maybe a little trip up the street and back might fix it.

Once you have it unstuck, I would avoid using the parking brake during cold spells.

 

I went to move my dads passat out of the drivway and it feels like the parking break is just stuck on ( i can put the handel up and down fine even tighten it up a few clicks) but its like its just not disengaging my dad complained of this once before during another cold snap but its about 17 today and thats going to be the high so there is not chance of it warming up

what should i do

i was thinking mabey it was water or moisture in the break line
i know how to flush the system but i want see whaty you all think before i go and do all that work.

The parking brake doesnt use the hydraulic line, so flushing the fluid will do nothing. the parking brake is actuated via a cable, which screws into the brake piston. silberwagen is correct in saying that a hairdrier might help if the problem is moisture related.

More likely though, is that the slider for the caliper have run out of lube/and or dirty. I'd first can a can of "brake parts cleaner" and spray the crap out of the brakes. If this doesnt work, disassemble the rear brakes and clean & relube the sliders.

 

The cables run thru a cover. The cover gets water in it and freezes. The cables can also rust. You need to manualy move the parking brake actuator at the rear wheel caliper. You will see the end of the cable attached to a lever on the caliper. Gently apply pressure to release it.

On older cars,we used to spray silicone lube into the cable covers.
