Slowing as I approached a four-way stop, my brakes failed to stop. I heard a loud noise (my husband, a mechanical engineer says it is the anti-lock brakes) and the brakes don't work. On the fourth braking attempt they worked. This is the third time this has happened. Each time was at a slow speed, after a rain, but not raining.
