About an hour ago a guy ran a red light and slammed into me. Some bystanders helped me roll my Z1000 to the side of the road, where numbers were exchanged (including those of witnesses - Thank God!). I'll have to get it towed as the fairing was rubbing against the front wheel, but of greater concern, the brakes didn't appear to work as I was rolling it down the hill into a driveway to get it off the road. I had to steer it into the kerb and drop it before it built up any more speed. Some specifics: When this happened, half of the brake lever had snapped off, but still had enough grip to pull the front brake. The engine was switched off and my zed was in neutral. The rear brake did not appear to work neither no matter how hard I tried. Later, when it was on the nature strip, I squeezed the brakes and it appears to grab as per normal. I was tempted to ride it home but didn't want to risk the brakes failing again. Would you have ridden it home? Can anyone enlighten me why this happened from a mechanical perspective? Do bike brakes operate differently from cars?
