Drop--re truing rotors, the few times I have had to do a slight truing, I used either a cleaned adjustable plier or even my hand, and just eyeballed it, and it was fine.
i prefer to have my levers engage half way down, I find it gives better modulation and finger hand force than instant application--hence there is more clearance between disc and pads, bonus being not so super critical on the exact trueness front
I fixed a neighbours bike recently, a shifting issue, and noticed his front wheel turned slowly with bike on stand. Sure enough, his hydraulic caliper was rubbing sightly, no pad adjustments available, and hardly discernable rotor to pad spacing. He had put anti theft skewers on and it needed a smidge of a loosen and wheel shift, we're talking itsy bit, but fixed the rubbing.
I only know BB7s, which have pad adjustments for both pads, but one really doesn't have to touch them for ages when set up properly.
