Brakes-why did they wear out like this

Looks like the pistons are not retracting. I'd at least change the brake fluid. It might not be a bad idea to rebuild or replace the calipers as well.

50,000 miles without the pistons retracting? I think not.

Klink is right, that's salt, almost for sure.

Not 50K without them retracting. Once they stop retracting properly the wear happens very quickly.

Two weekends ago I changed the calipers and rotors on a friend's daughter's Nissan Altima. She just had the pads and rotors replaced about 5K ago, but they were making a horrible metal on metal sound, so they brought the car by so we could check it out in my heated garage. The outside pads looked like brand new and the insides did not have a trace of pad material left and the rotors were destroyed. We popped the pistons out of the calipers and they were severely corroded.
