Brake light flashes and chimes on 1996 Buick Park Avenue

Brake light flashes and chimes to alert that the parking brake is activated but the brake is actually not engaged. how do i stop the chiming?

Check the brake fluid in the master cylinder reservoir. If the brake fluid is low the same warning light and chime will sound on your 1996 Buick Park Avenue. Use only DOT-3 brake fluid to top off your master cylinder if it is low.
