Just got to work in the S4, opened the car door and thought... "that's a strange brake-like smell"
Looked at the back wheel and it was smoking! Looks like the brake has been caught on while I've been driving. I thought it was weird when I pulled the handbrake on and it was really 'easy' to activate. Thought it might need adjusting, but I guess not.
Is there a quick way of releasing it as I'll be stuck at work otherwise...
