The "BRAKE" light monitors more than just whether the parking brake is applied. Do not ignore this. The most common reason is low brake fluid.
Air in any of the lines can set off the alarm, also.
Check out the brakes or have someone check them for you.
Take care.
1st ck your brake fluid level. then the rest of the breaks. possible low fluid level
