A bag dispenser includes a frame with a roller portion for receiving a bag roll defined by a plurality of bags attached to a leading bag to be dispensed, the roller defining a longitudinal axis. A brake plate is configured to capture the leading bag against the frame for providing frictional force on the leading bag to limit sliding thereof, the brake plate pivotally attached to the frame via a pivot arm, the brake plate pivotable with respect to the frame between a non-pivoted friction-application position and a pivoted bag roll-installment position, the pivot arm configured to pivot with respect to the frame along a pivot plane generally perpendicular to the longitudinal axis.
