My rear wheels are seized up a bit from all the snow and ice. The front wheels turn fine. The car's been sitting for maybe 2 days since it was last used (when I couldn't get it out of the street on Sunday morning, last time I used it before that was Friday evening). When they're on the concrete, they spun a little bit, but when on the snow they don't/hardly turn.

I had brand new front and back brakes 2 weeks ago during a Major service, and they have been fine until now.

I've just read this thread on a renault site that says to hit the rear drum with a hammer to unseize it or something. Will this work? Am I taking that wheel off?

a few years ago i had the same problem with a work car (punto) the rac man gave it a few wacks to the back of the drum and that sorted it.

be careful though!

just drive it mine did that on sunday it soon snapped free

Yay I got it free. Smacked it with a mallet and some wood a little bit, sprayed de icer on and shovelled

Where do you smack it with a mallet? On the actual tyre?

on the back of the drum, which the ST doesnt have :-s

Hmmmm we shall see, drove to my mates house and my back left wheel was dragging along, pulled over and saw my back left brake disc BRIGHT RED and sizzling all over the joint...was pretty scared.
