Potenza and below use a steel 5mm allen..Centaur and Potenza. All above use a SR part, aluminum and T25..

Yes you can, what you can do also is just use brake caliper nuts aswell, some campagnolo brake calipers come with extra Txx nuts.

No need to pull back the hood. Just insert a long Torx head or allen head driver down side along the lever. Goes straight to the bolt, without peeling hood back.
