How can a recumbent tadpole trike brake three wheels with only two levers? So this is probably a terrible idea, but I was looking at recumbent tadpoles recently and it just clicked. I would have two brake levers but three wheels. I would need to have to...

1.) Calibrate the two front brakes off of a single lever which I suspect would be maddening

2.) Only brake using the back wheel and one front wheel (turning when braking sounds like a bad idea)

3.) Forgo braking on the rear wheel since on bikes the front wheel does most braking. I suspect this is similar for trikes. I would instead be able to actuate the brakes on the left wheel with the left lever, right wheel with the right lever etc...

So, the question is, what is the general brake setup for tadpole trikes?
Most are set up with one lever that works two brakes at the same time. There are lots of different styles, such as this one for example.



You can see that it has 2 ferrules instead of 1, most commonly used on dual disc brakes. There are other models that differ somewhat visually but the idea is the same. Many Trike levers also have a push button locking mechanism that functions like a parking brake so that it cant roll while engaged.
