In the case of the main gear, braking (at a reduced pressure) is applied
when the shock struts extend.  Most nosewheels are not equipped with
brakes, so some sort of snubbing (rub strip) causes the wheel to stop
spinning.  Nose wheels generally retract fwd/aft, so that gyroscopic
precession is not a factor...
