Back in 1968 (about) there was an AD on the Beech Musketeer
because the parking brake would vibrate and engage during
flight, the system worked by locking the pressure from
applied normal brakes in the master cylinders. When you
landed, you could have one or both main wheels locked or
just dragging, depending on whether you had applied pressure
to the brakes in flight. This happened to me at SPI in the
winter, landing on Rwy 22 which was partially snow and ice
packed. I touched down on the ice and everything was fine
until I hit a dry area. The airplane yawed about 20 degrees
to the right in just a second or two. Full left rudder and
power straightened it out. When I got to the ramp and we
examined the airplane, 4 of the six plies in the new tire
had been cut through and flat spotted. This may have one of
the incidents that prompted the AD note.

Cirrus could have a similar problem.
