lost one brake on the 210 on rollllllllll-ouuuuut at Oshkosh for the airshow. got stopped for the turnout in front of the tower to be directed to the north tie-down. had to do a 270 degree turn to turn north. this didn't faze the ground guys a bit - I still wonder why. Nose wheel steering was enough for gradual turns plus power bursts (when no-one behind us). You ought to try leaving your foot off one of the brakes to see what it's like - not nearly the disaster you'd think - in easy conditions.
Cranking in full deflection with rudder and nose-wheel steering while touching the toe-brake with the other foot is a little tricky, but if you pay attention it works - somewhat.
Back at PWK we found one brake used lightly did help while there was rudder, but not slower, I got it to the shop with power bursts and nosewheel steering
