its sort of hard to tell from your pictures. it looks like the pads have little to no material left on them which could account for the gouging...but my gut is telling me that from the redish color of your rotors and the streaking that your caliper has locked up. when pads get that low, you run the risk of locking the caliper up...seen it time in/out. what you need to do is pop the master cylinder cap, then pry the caliper open, to make sure it still functions correctly. if it still works fine, then i would recommend changing your pads, and you can probably get away with the current condition of the rotors, they just might squeek while the new pads are wearing the grooves smooth.

what were you doing when you noticed the condition of the brakes?
