Default Thread pitch of brake caliper bleeder screws?

After contemplating the replacement of a snapped bleeder screw today, I decided I would be best off putting Speed Bleeders in all the calipers. What pitch do the FC calipers take? Are they all the same all around? What about 4-pot vs single piston fronts?

Fronts are 8mm x 1.0.
Rears are 7mm x 1.0 - both of them.

These are for the "big brakes" - 4-piston fronts and vented rears.

considering you have a snapped bleeder...
be aware that you have to be gentle to speed bleeders! they are much more fragile than standard ones. hand tight with a very small wrench.

Haha yeah, I'm usually pretty gentle with them, but this one was rusted shut, and I got frustrated and gave it a huge tug (giggity) and it broke off. I figure if I start out with non-rusty ones, we'll be all good .
