Noisy juddery brakes

[OakLeaf]

No, they're dual-pivot. Shimano 105. Do those still need toed in?

[nod to the regionalism thread... it used to drive me crazy when people omitted "to be" after "need," and now I'm doing it]

I'll check the mounting bolts for sure... but where do I find a torque spec?

Thanks!

EDIT: found the torque spec on Shimano's site. 8-10 Nm (69-87 in-lbs)

EDIT AGAIN: I took a closer look at the pads, and what it is, he rotated them - not sure if that's the proper term, but turned them upside down, so where they were worn thinner at the top and thicker at the bottom to match the shape of the rim, now they're the opposite. Will they quickly wear back down to where they aren't vibrating, or is the increased life not worth it? Should I do this periodically - before the wear is so pronounced - like every 500 or so, to increase the life of the pads without them being so far off the shape of the rims?
