  We study the stability and breakup of liquid bridges with a free contact line
on a surface with contact-angle hysteresis under zero-gravity conditions.
Theoretical predictions of the stability limits are validated by experimental
measurements. Experiments are conducted in a water-methanol-silicon oil system
where the gravity force is offset by buoyancy. We highlight cases where
stability is lost during the transition from a pinned-pinned to pinned-free
interface when the receding contact angle is approached---rather than a
critical state, indicating that the breakup length is not always associated
with the static maximum-length stability limit. We demonstrate that the dynamic
contact angle controls the contact-line radius following stability loss, and
that interface evolution following stability loss can increase the
dispensed-drop size if the contact angle is fixed.
