Abstract A braking power modulator is coupled to the brake lever of a brake operating device for easy adjustment and viewing. The braking power modulator is preferably adjustable to provide different braking powers for different riders or different road conditions. The braking power modulator basically includes a mounting member, a brake lever, a biasing member, a modulating member and an adjusting member. The mounting member is adapted to be coupled to a handlebar of a bicycle, and has a cable passageway. The adjusting member engages the biasing member to change the pre-set compression force of the biasing member without changing the predetermined modulator stroke of the second blocking portion.
