Brakes, why can't you just work?!

Seems about right for me to have another problem with my brakes going by the amount of threads on the topic by everyone else below 
I have tektro aurigua comp brakes and they have both been recently bled (by me). Recent as in about a month ago. I noticed today while I was out fettling with my bike after a ride earlier, that there seemed to be a tiny amount of fluid leaking out of a screw that holds down the reservoir (on both brakes). This only happens when I pull the lever so it's not constant. The diaphragm is seated properly, as is the reservoir cap, and the two screws are tightened yet somehow fluid is leaking out. :?
Any help (again!) would be great. Someone suggested using loctite on the screw thread, would this sort it? I don't want to contaminate the fluid. Thanks, Adam.

People fiddling with their brakes seems to cause more problems than anything else.I don't do smileys.

I didn't think o-rings could be made that small! I had a look for an exploded diagram but there was nothing online. I could understand losing 1 o-ring but not 4 as none of the other screws have washers/o-rings0

Ahh but I had a good reason!
probably right though! I can safely say that my brakes definitely needed bled however! 0 -

Pics. it will just be residue moving as the diaphram moves."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

It is the tiny allen key screw on the right. Exact same on the other brake. When I squeze the lever I can see a bubble or two under the screw head0
