Sounds Like a problem with your sensors or elictrical components on your dash. Have you had issues with Water? We also have the 96 Achieva and I need to park it nose up to prevent water damage when it rains on floor..Ecspecially the drivers side
Still take to a qualified mechanic for a diagnostic. Ask for pricing in advance as some will do the service for free but most charge 50-80 or an hours labor :( Just to hook up to the machine.
Check the brake light fuse first. Then check for a bad brake light switch at the brake pedal.
