    New question here. Question about how hydraulic brakes work

    I'm planning on swapping my mechanical disk brakes to hydraulic brakes.

    Question: Are there hydraulic brakes in which one hand lever actuates both F & R brakes at the same time or are there always front and rear (left and right) hand levers?

    Most hydraulic brakes I've come across (Avid Elixir, Shimanos, Maguras) are 'individually' actuated (not one hand lever). This is better in my opinion, since you can control how much braking you want out of each brake.

    Magura Big can be set up to use two brake calipers with one lever, it's used on 3 wheel recumbent bikes, pedicabs and rickshaws where you'd have it set up on 2 front wheels or 2 back wheels.
    You wouldn't use this system on a bicycle as you couldn't modulate the power between the front and back, there would be equal power going to both brakes, as the front brake on a bicycle has more stopping power then the rear brake, if you did you'd be locking up the back wheel all of the time.

    Here's a photo of the Magura Big set up on a 3 wheel recumbent.

    There is dual pull cable brake levers that can be used on bicycles as well as 3 wheel recumbent bikes, pedicabs and rickshaws.
    With the dual pull cable brake lever on a bicycle you can modulate the power between front and back brake by changing the cable tension or pad position on one brake so it engages first, by the time the second brake engages the first brake that engaged is already giving more braking power.
