Well, my quad and I went for a heck of ride the other day when my brakes failed on a very steep mountain. It started rolling backward, hit a rut, and took air. I somehow managed to hang on to that baby for a full back flip! eace!: After that, I jumped off and it kept going. Believe it or not, it's fine! A little brake fluid for the quad and some Aleve for me and we're both back to normal.
