It's a fairly common issue that affects a number of cars. When you leave your i10 parked up with the handbrake on for an extended period, the brake discs corrode and the pads stick to the discs. This is more likely to happen in wet weather. We'd recommend leaving your car in gear without the handbrake on – it might feel unnerving but if it's in gear, it won't move. You could also try changing the pads – some are more prone to sticking than others.
