Various embodiments of an apparatus and method for dispensing elongated material, such as tape, from a spool or roll of such material are disclosed. In one embodiment, a dispenser includes a rotatable spindle for supporting the roll of material and a brake assembly operable to provide a braking force to the spindle. The brake assembly desirably includes a rotor coupled to the spindle and a caliper configured to apply a braking force to the rotor, thereby slowing or preventing rotation of the spindle. The spindle can include at least one roll retainer projecting radially outwardly from the spindle. The roll retainer is configured to frictionally engage an inner surface of a core of the roll to prevent movement of the roll relative to the spindle when material is being dispensed from the roll, yet allow an operator to remove the core from the spindle.
