Basically it's like Matt said above. When you release the brakes (take
your foot off the pedal), and you still feel some dragging at low speed,
that's collapsed hoses. The thing is, if you ignore that drag when the brakes
are still cold, the next time you use them (once they've warmed up), the drag
is even more noticeable, because the fluid has expanded in the lines
building pressure and keeping the calipers energized.
In my case, I thought the PO had replaced the master cylinder with the
wrong one (1 with compensating valves/ports according to Bentley), so I
swapped it again, only to have the same issue. At this point, only the hoses
hadn't been replaced, as it now had a new master cylinder, new calipers, and
new front rotors (they were worn below their limit), so I replaced the hoses,
and everything was good to go. Lesson learned, that these hoses collapse
internally. I'd never ran into it before, but then all of my experience prior
was with domestic vehicles, and those crack externally when they go bad.
