Driving a new 2010 Toyota Fj Cruiser with approximately 600 miles on the odometer. Moderate rain. When turning off a paved roadway onto a flat, wet, and muddy surface I had the experience of total momentary brake failure. This occurred as my left front tire left the road surface and hit the slick mud. My speed was under 20 mph and I was able to regain braking power by releasing the brake and then re-applying it. My assumption at the time was it was the result of some kind of weird abs behavior. I was applying the brakes very lightly to gradually slow my vehicle. The brakes behaved normally until the first tire hit the slick muddy surface. Somehow the system caused all 4 wheels to lose all braking power.
