Controlling the amount of braking applied from the keyboard may be a good thing, however some joystick bindings do interesting things to the brakes to give differential braking effects. I actually have two axises assigned as toe brakes on my rudder pedals. Point being this won't be a generic solution. > One thing I may ask about as well is the ability to write a rain > condition into it, with reduced braking effect.

Simulating braking coefficients by limiting /controls/gear/brake-* isn't the best way to go. For JSBSim aircraft static friction coefficients for each gear can be adjusted on the fly by changing fdm/jsbsim/gear/unit[*]/static_friction_coeff.
