All foolin' aside, I think you'll find all brake fluid reservoirs have
some form of venting. If they didn't, the rising and dropping levels of
fluid (or fluif, as it is better known on the list) would form either
mild compression or vacuum inside the reservoir, one of which could
possibly cause a shoe or pad to drag, the other could draw air into the
system through any "weak point". The levels have to rise and drop as you
apply the brakes, as the shoes and pads wear, and as temperatures vary.
But, hey, I ain't no engineer!
