Hard to put in words, but because you need less force on the levers you can better feel the wheels before they lockup. The same way you would feel that your wheels are almost locking up with cantilevers, but with disks it's like you have more warning AND it's easier to control.


It's all in how much pressure you apply to the levers, there's a sweet spot where you have maximum force on the levers (the pads are almost locking the disks) but not enough to completely jam the disks. There's no such thing as pumping the brakes on a bike because the system is absurdly smaller/shorter then what you have in cars, so things are much more instantaneous.
