Brakes problem
1997 Mercedes Benz E220 Automatic 78595 miles

Hi i changed the tyre on my mercedes recently.this is the back right hand tyre and replaced it with a spare tyre.fortunately i did this from home.after the change i tried to drive off and the car still felf like it was still in brake and yet it wasnt.i narrowed it down to the tyre i had changed and i had to remove the tyre again only to realise the brake pad was stuck on the disc even when the hand brake was released.is there any DIY way of getting this sorted and any advise for future tyre changes.thank you
