Just got home from college, and there's smoke p!*sing from my passenger side brakes, going for about 5 minutes, I threw some water on it and it all steamed up and started hissing like mad. Still smoking now after 15 minutes. The engine block is hot too as is the collant tank so I took the cap off that and that let out steam too although the water wasn't bubbling. Just had it a week, don't fancy it blowing up, anyone know what's wrong or what I should do? The smoke seems to be coming from behind the brake disk.
