This is a cool idea. But one must be careful not to pump much because the
lid on the resevoir will pop off. I think it might be good to make a "thing"
to hold the lid on tightly when doing this.

Subject: Brake bleeding tip
On the subject of brake bleeding - A good friend of mine recently
built a
very effective bleeding aid. Here's a description:
Parts needed:
extra brake fluid reservoir cap
brass .125 inch pipe to .25 inch hose barb fitting
epoxy
length of .25 inch diameter hose
plastic pump-up spayer (the sort used for pesticide or fertilizer - found in
most garder centers, hardware stores etc)
Drill hole in top of spare reservoir cap just large enough to fit hose barb
end of brass fitting - insert hose barb and seal with epoxy - connect hose
between barb and sprayer - add brake fluid to sprayer, pump up just enough
to start fluid flowing through hose - install modified cap onto reservoir -
pump up sprayer moderately. Now open bleeder valves in turn to bleed brakes.
Fluid will flow nicely, and the sprayer will keep the reservoir full.
Total cost for bleeding aid: about $15
Note: Hose barb and hose size may vary depending on sprayer model, also do
not pump the sprayer up too much or the brake fluid will foam as it enters
the reservoir.
