It is the same braking system as all BBW units. Working at IAI, you have access to one of the precursor, ie GLF4.
If you are talking about NSWS then this is another story , but again, Airbus is doing it for a while, even Learjet had 'akindof' device.
For the brakes, they brake when needed, with the power of Carbon brakes,a bit touchy as usual when very light; not as the GLF5.
What is behind your question ?
