A self-adjusting earth-boring tool includes a body carrying cutting elements and an actuation device disposed at least partially within the body. The actuation device may include a first fluid chamber, a second fluid chamber, a first reciprocating member, and a second reciprocating member. The first and second reciprocating members may divide portions of the first fluid chamber from portions of the second fluid chamber. A connection member may be attached to both of the first and second reciprocating members and may have a drilling element removably coupled thereto. A first fluid flow path may extend from the second fluid chamber to the first fluid chamber. A second fluid flow path may extend from the first fluid chamber to the second fluid chamber.
