An apparatus for applying a braking force to a brake disc using a brake pad (22;422), comprising: a lever configured to rotate about a first fulcrum; a pressing member attached to said lever and for urging a brake pad against a brake disc; a link member attached to said pressing member and configured to rotate about a second fulcrum in such a manner that said brake pad remains substantially parallel to said brake disc while said lever rotates about said first fulcrum; and a rotatable input member configured to rotate a first member, wherein, in use, rotation of said first member causes movement of an actuating member along an first axis, and said axial movement of said actuating member causes said lever to rotate about said first fulcrum for applying a braking force to said brake disc; characterised in that the apparatus further comprises a return drive comprising: a first movable member configured to move a limited and predetermined distance along a second axis between a first stop and a second stop; and a second movable member interference fit into said first movable member and operatively connected to said lever (50;53) such that rotation of said lever (50;53) about said first fulcrum (50;53) causes said second movable member to move along said second axis; wherein: upon rotation of said lever (50;53) in a first rotational direction, said first movable member and said second movable member move together until said first movable member reaches said first stop, at which point any further rotation of said lever (50;53) in said first rotational direction will cause said second movable member to overcome said interference fit and slide through said first movable member; and upon rotation of said lever (50;53) in a second, opposite rotational direction, said first movable member and said second movable member move together until said first movable member reaches said second stop. a lever configured to rotate about a first fulcrum;
