Our caravan is kept on the drive at home - the drive is quite steep and without the handbrake the 'van would take up residence over the road! This poses a problem over the winter as I know the handbrake is best left off to avoid the brakes seizing. I have wheel chocks but with the wheel clamp on I can only use one whilst the wheel clamp is on. I have also read its a good idea to rotate the wheels but agin would need the handbrake off to do this. Any suggestions please? I have thought about peiodically (every month or so) removing the wheel clamp, chocking the wheels and taking the handbrake off for a short while - would this be sufficient?
