96 brake light

The brake warning light on my 96 comes on when I go turn to the right. Turn to the left and it goes off. Is something loose that I can not see?
Thanks

i'll say it's low..theres a switch in there that tells it it's full when added...you may have a leak somewhere that it's using brake fluid..can either be master cylender going out,or brake line leaking ,or wheel cylinder leaking..good luck...
