Glovebox light, dont have one on Brava, should be same as on Marea, remove glovebox and see that the plug is attached (and the bulb is intact).
Boot light, dont have one so hard to say, boot switch?.
Brakelight, if it is original, the bulbs might be okay, but the whole bulb assembly is pressfit and has corroded the leads off the bulbs.
Diassembled and replaced mine with normal 5mm white leds.
Or the contacts on the boot are bad, but my money is on corrosion damage.
