Hi all Drove my car last night, absolutely fine. This morning I drive it off the driveway and the rear left wheel is stuck! Would this be a handbrake issue or general stuck caliper? I tried rocking it but it didn't free up! Also threw boiling water over it in case it was frozen but that made no difference. I don't really know anything when it comes to brakes and this time of year, most garages are shut - and I can't get it there. Cheers for any help!
