i could, because i've ridden without a brake. It helped me to clean out my flat tailwhips in old times, because i hate landing on brake. But for now, brake keeps my foot from touching the wheel when i'm riding skier style.
somtimes i do just when the POS isnt working good and rattles like a jungle bell. but it sucks you have to keep your feet away from the wheel. but tiretaps are i little harder but more fun i think. fakie tricks are a billion times better too.
