So assuming we wanna mimic a hand squeezing a brake lever of a bike, what can be used to accomplish that with some DC motors/Servos?
The whole goal is to squeeze the lever, not design a robotic hand.
Servo pulling a bit of string connected to the brake lever?
How far does the lever move? How much pressure is needed to move it? Do you really need a squeezing motion or just something to move the lever?

Does the lever even need to be there when a motor/servo can be put directly on the brake?
There are Arduino projects that control hydraulics.
An actuator could work on the lever.

Well a string won't work, it's a hydraulic disc brake so I need some torque to be applied the whole way through. about 2 inches I believe

unfortunately the lever need to be there, it will keep the pumping action while I work on the brakes.
could you clarify what kind of actuator would do the job best? I'm thinking either a geared down motor or a solenoid. what how would I connect that to the lever? I'm stuck in the area between the actuator and the lever
