Jobst Brandt asked:

Could you explain to what "linear pull" refers? That in contrast to
other brakes.

Actually, the proper distinction is "linear pull" _cantilevers_ as
distinct from traditional center-pull cantilevers.

Center-pull brakes, either calipers or cantilevers are distinctly
non-linear in response.

I cover this in some detail at: http://sheldonbrown.com/cantilever-geometry.

Linear-pull cantilevers, such as Shimano's "V-Brakes" are, by comparison
basically linear in terms of pad movement vs cable movement.

Traditional sidepulls are also linear in response, but to refer to them
as "linear pull" brakes would be sort of like calling an Ashtabula crank
a "cotterless" crank: technically correct, but idiomatically inappropriate.
