Advice re binding brake
Discussion
I noticed one of my rear disc brakes was getting seriously hotter than the rest so jacked it up and sure enough, I was meeting a lot of resistance when turning the wheel by hand. Took it to the garage who told me that they found that the caliper slider was stuck fast so freed it up using heat, cleaned up the slider pins and they have covered it all in copper grease (which I now believe is totally the wrong grease to use)
Anyway, I picked the car up, drove home about 8 miles and the 'fixed' brake was boiling hot. Way worse than before! Jacked it up and now I can't move the wheel at all by hand.
I'm now not wanting to drive it anywhere further than a mile or so to the nearest garage, but what on earth could it be causing it to stick, given that it's supposedly been freed up?

Thanks for the replies.
My apologies, I seem to have been hasty in saying the wheel wouldn't spin by hand. Mustn't have jacked it up enough. I've now been out for multiple drives and jacked it up a couple of times and the wheel does spin much more freely. However.... the disc is getting excessively hot under normal driving. The brake doesn't appear to be binding/stuck on, as I've driven for a few miles barely touching the brakes and after checking the disc it's lukewarm, like the other discs, but as soon as I start driving and braking as normal, the affected rear disc gets very very hot, much hotter than the other rear, and even hotter than the fronts. Could it be that following the repair, the caliper/slider is now so freed up that the brake is working almost too well, and somehow taking the priority of the braking force when I depress the pedal? I suppose it would have made sense to grease up all of the calipers rather than just this one??
