    Do you mean the brake lights at the rear of thee car are remaining on all the time, if so I would think the brake light switch has failed / shorted. If the brake light on the dash board is remaining illuminated I would check the brake fluid level in the fluid reservoir.

    Looks like the brake light switch is bad,.if the cruse control won't work it is the switch.
