I have been rebuilding my brake system (drum/drum) and finally got the
master cylinder cleaned up. What a mess!! It had been sitting out side
for many years. About 1/4 inch of rusty sludge in the bottom of the
reservoir. It cleaned up rather nice with a lot of lacquer thinner and a
final diluted muriatic acid (HCl) dip. Luckily the cylinder portion itself
is in good shape with minimal honing.
Anyway... the nut portion on the cap was badly knarled so I used a file to
try and square up the surfaces again. I notice a pinhole on two opposite
faces of the nut. Did I file to far or are these breather holes? I forgot
to look before I filed.
As an aside.. I was wondering why one couldn't make a "dehydrating bag" to
keep water out of the brake fluid. They make what is called a molecular
sieve. These are small, inert, pellets which have an affinity for water
sized or smaller molecules. I use them where I work to keep water out of
various liquid reagents. It seems to me that one could make a small bag or
pouch of these sieves with a retrieval string. Place the bag in the brake
master cylinder reservoir and keep moisture from leaking into the system (at
least from that location). This could even be used in the fuel tank to soak
up moisture.
Hmmmmmmm maybe a new ___.com is in order.
Any thoughts, comments,.....
I think I am going to try it in a glass beaker full of brake fluid first and
test the idea by adding small amounts (mists) of water and watch what
happens with time.
Happy Holidays to all
