Thx Franzgo,

The anodizing is a good idea.

I am currently using Dot5 as well in my classic mono. Expensive, but i like it
as it is so benign.  I wonder if beringer can use it (they spec dot4).

I talked with beringer at osh, as well as emailing them, and in those 
interactions
they claimed 18-20psi is fine. Did you find a the minimum pressure documented
somewhere?

Thx,
Pete

longer uses airtube and, in consequence requires a far higher pressure (around
2 bar) than the previous recommended pressure (1,3 bar). For grass strips,
a higher pressure is not really an issue, but for hard landing surfaces with the
monowheel I really fear that it is not adapted (Bouncing and bouncing again...)

hand. And maybe it would be profitable to use 2017 alloy with anodization finish
to keep it away from rust. On my aircraft I have found interesting to use 
Silicon
Oil (brand AUTOMEC, Dot 5.0) instead of classic brake oils, in order to
chase moisture from the brake pipe and also to protect all gaskets from wearing
to fast.  For one year now I find that the caliper has less tendancy to grip
than with the old sticky (and hygroscopic) brake liquid...
