Are you saying that every time you replace the bulb, it works for a few
times when the brakes are applied then the bulb actually fails? When this
happens, does the bulb work at all i.e., would it light if you ran a pair of
leads from the battery to the bulb by itself?
A couple of thoughts come to mind....If each replacement bulb really does
fail then I would suspect the bulbs you're using. Is it possible that you're
using 6 volt bulbs? If you're taking the replacement bulbs out of a package
of several bulbs, try using another one of those bulbs on the other side
(brake light) as a replacement just as a test or, better yet, take the battery
test leads and see how long one the package bulbs will stay lit from direct
Weird things can happen from defective bulbs. Some of the more common are a
tailight becoming very bright on one side when the brakes are applied or one
brake light turning off when the brakes are applied but to consistently burn
out a 12 volt filament bulb with 12 volts (or even 13.5 to 14.5 volts if the
alternator is charging) seems to point to defective bulbs.
Good luck...keep us updated on what you find!

I am having an issue where everything back there
works, then the bulb fails when the brake is applied.
