Break light comes on while turning 2000 Sienna

Whenever I turn my 2000 Sienna, break light comes on for 1-2 secs and then goes away by itself. It happens more on right turn.
Please help.

Thanks

Check tour brake fluid level, it might bd low.

I'm not a mechanic, but another thing that might be causing a problem is that your ABS monitors the rotational speed of your tires (This is also how it checks tire inflation pressure) and when you go around corners your tires rotate at different speeds. How fast were you cornering and could the fluid have sloshed to one side of the reservior? Do you have different tires on front and back? If your tire inflation light also stays on, check to see how good a match your tires are.
