Would one not buy space to align the caliper with a few lever squeezes to reposition the pistons outward?
I keep hearing about thicker rotors and how they reduce pad clearance. But I don't understand how that could be: surely there must be room for each piston to move 0.1mm outward without bottoming out. Or, with a well bled system and brand new pads, maybe you'd have to let out a drop of brake fluid to buy the space?
I think I have a good grasp of how brakes work, but am also not the most logical person to ever touch a bike so I'm hoping to learn!
