Do you have anti-lock brakes? Is the light red or yellow?

Check that the parking brake is fully released, check the fluid level in the reservoir, (don't fill it to the top; just be sure it's above the "min" mark. Unplug the pressure-differential valve on the frame under the master cylinder. If that makes the light go off there is a leak or something else causing unequal pressures in the two hydraulic systems.
