Since I really wanto to do this job by myself, I've already searched old post, but I still have some question:

CALIPER BOLT: it's suggested also in my Haynes Manual to utilize new bolt for the calper mounting (2 each bolt if I'm not wrong) and also for the caliper part that hold the pads (1 or 2 bolt). Is really necessary to purchase new bolt? Probably it's suggested, but do you really do it?
Since I'll utilize aftermarket product (Brembo) may be the new caliper bolt will not be included in the kit.

STAINLESS STEEL HOSES: does someone have already utilized them? Is it really suggested? How difficoult is a DIY?

BRAKE SENSOR: can I utilize the old one or is better to purchase new one?

haynes manual suggestion: they suggest to utilize special grease in way of pads support and also special anti-corrosive product in way of hub (rear to brake disc). Do you suggest something?

I thank you all of you Guys.

FYI: I'utilize Brembo Max for the front brake disk. Rear disc/pads are still good.
