Over the past summer I went through hell to get almost everything fixed and now I got my rear right wheel leaking brake fluid, now mid you the brakes were bled and the prop valve and M.S. were replaced, the car stops perfect, but is it possible that the mechanic that bled and fixed my rear brakes might have simply failed to tighten up the right rear brake valve line while bleeding it?...I can clearly see some kind of fluid coming out of the drum, but nowhere else.

Thanks in advance!

 

That would be great if the bleeder just needed to be tightened. Usually this is an indication of a leaking wheel cylinder. You will have to get a closer look and find were the fluid is coming from.
