If it is not low, locate the connector that plugs into the brake fluid reservoir and unplug it. See if the light goes off after restarting the engine once. if still on, jump out the two pins in the connector. The light should go out either just unplugged or jumped in most cases. I rarely see any other cause for a brake light illuminated. Most times the reservoir float is no good or stuck.
