Answer 1

you probably got a beaver stuck in between your tires

Answer 2

changing the brakes didn't cause that too happen to it,you got a converter going bad or something is clogging it,take it by any muffler shop and have then check it those should never smoke like that,especially none of those cars,and not from changing the brakes not unless he got brake fluid on the converter,good luck.

Answer 3

its nothing to do with brakes

wetting is due to condensation

smoke is just water vapor
