IS it the BRAKE LIGHT or the Parking Brake Light? If it is the BRAKE LIGHT, then your pedal must be going down far enough to hit a sensor that sets off the brake light to tell you your brakes need serviced. Normally this means you are low on brake fluid. If you are low on brake fluid FIND OUT WHY! You may have excessive brake pad wear, or a leaking brake cylinder, or your master cylinder may be going out. If you keep pumping the brakes and then stand on it hard, feel for the pedal to eventually go soft, if it does, then normally the seals in the master cylinder are going out. If you pump the brakes and the pedal never gets hard, then you have a serious brake fluid leak. If the Parkign Brake light stays on, then your parking brake is not fully releasing, at least where the contacts are to remind you it is on. This can be adjusted.
