Default Brake warning light

99 RX300 my brake warning light on the dash came on every morning. I thought it was emergency brake but it doesn't go away.

Welcome to ClubLexus.

The most common reason is a normal drop in brake fluid, caused by the brake pads wearing and the wheel brake cyllinders expanding because of this. This would be the first thing to check, and then top up the brake fluid to the normal level. If the brake fluid is already at the normal level, the next thing to try is to disconnect the level sensor at the brake fluid supply container, to see if the float sensor is defective.
