For simplicity and ease of storage eliminate the sprayer. DRILL and
install the tire valve stem on the cap of the master cylinder.
Use a tire pump to pressurize the master cylinder. On a Vanagon you need
no more than 5-10 lbs.
At the brake cylinder end use a catch cup smaller than the size of the
brake reservoir, which will provide a good indication of when the brake
reservoir may need filling. (to prevent air entering the brake system).
Buy one of the valve stems that comes with a metal slotted cap to loosen
the valve stem seal.
This should cost less than 5 bucks at a tire shop.
Use the slotted metal cap at the completion of the bleeding project to
loosen the seal in the stem just enough to allow the master cylinder to
breath again.
The modified brake cylinder cap will stay installed/stored on the brake
reservoir.
This will eliminate storage, the cost of a garden sprayer & introduce
simplicity.
Life is good
