Hmmm...another problem? dont tell me that!

I was told specifically it had to be warped or uneven rotors(pad left deposit on the surface). It vibrates about 2 seconds after i apply moderate braking at a good speed(at least 20mph). Does it all the way up to 70+. So this cant be warped rotors? It only happens when i apply brake. I cant think of what else it could be.

Oh, the part where the hub was staked, it said take a chisel and bend it up. When i did, it chipped off, so i cant restake it in that location. I'll have to over tighten the hub nut or under tighten it and stake it with the remaining circumference of the hub "rim".
