Are you sure that it's the tyre pressure light? If your car is a first generation, then you are correct, the light is yellow and not red. Second generation have a red "run flat " indicator.
The brake warning symbol is similar to the tyre pressure monitor light and should come on when the handbrake is applied. It will also come on if the brake fluid is low or, together with the ABS and stability control lamps, if there is a problem with a wheel sensor or other ABS components
