Check the bulbs, check the fuse, check the brake light switch, in that order.
The brake lights are a separate circuit from the tail lights. If the bulbs and fuse checks okay, I would suspect the brake light switch is at fault.
I am having the same trouble. My brake lights work with the light switch for nighttime driving, but only far right brake light works when i pres brake pedal. Reverse lights dont work at all. Turn signals and hazard light work.
When my Volvo broke an alternator drive belt the majority of the warning lights came on.
brake switch ???
fuse, bulbs
Most likely no brake lights would be due to a faulty switch on the brake pedal or a bad fuse.

Blown fuse or bad brake light switch?
1987 volvo 240dl automatic backup lights don't work,fuze and bulbs ok, how do I trouble shoot?
brake light switch would be most common cause
check the fuse for the brake lights, they have thier own. also check the brake light switch at the at the top of the brake petal
The BOO (Brake On/Off) Switch may need to be replaced. If it is bad, it would cause the brake lights to NOT illuminate when the brake pedal is applied.
