A brake operating device for a bicycle of a drop type handle bar, has a hollow shaft at the foremost end of a main lever supported swingably to a bracket member. The hollow shaft supports a retaining member for one end of a control wire the other end of which is connected to the bicycle brake. An auxiliary lever is supported swingably to the bracket member around a pivot coaxial with a pivot around which the main lever swings, and is provided at the head with an engaging shaft parallel to the common axis of the pivots and engageable with the hollow shaft. The engaging shaft is fit into the hollow shaft to thereby operate the auxiliary lever in association with the main lever.
