Advice on Changing Pads in a Parking lot

Final (hopefully) update. Everything is in, it all works well. Bedding in the pads fairly soon, which is something I didn't do last time I put in pads, so hopefully it'll help. These pads did have probably close to 10k miles on them, so I guess that's the life of the brakes?
No!
I have a M/T and I think it's possible to get 8 or 10 times that amount of miles out of a set of pads in street duty.
And I cannot for the life of me, imagine how a bent frame can cause premature brake pad wear. A pull while driving, yes. Premature pad wear, no!
Go back to posts 35 and 36, something is wrong, with the brakes!
