Thanks, Jeff.
I'll double check the parking break.
My biggest head scratcher was that there was NO fluid anywhere.
Not under either master cylinder. Not on the floor panels. Not on the ground. None.
With the aid of a hangar-neighbor who happens to be an A&P and by even greater stroke of good fortune, has 15 years of experience rebuilding 337's, I topped off the Right Master (it was apparently about 2/3) empty.
Still no right break.
Our next move was to reverse-bleed the right break system.
10 minutes later...perfect right break.
So I had a problem. I found a solution (with the help of a lot of very nice folks ...THANK YOU ALL)
Now all I lack is figuring out the cause.
Break fluid doesnt evaporate so it had to go somewhere.
Since it isnt enywhere else...I gotta assume that the escaping fluid is pooled in the belly as suggested by Roger.
George Brown (my hangar neighbor) says that there is a swivel union where the gear rotates into the gear bay when retracted and that can weep fluid and make it "vanish".
Whereas I certainly have no data-points to argue against that possibility, I have difficulty imagining a "weeper" taking my break from good to gone seemingly overnight.
Needless to say....I'm racking up the hobbs time just driving around the taxi-ways waving at people as they gawk and greet me with the "What the heck is that?" look on the faces....which I am growing accustomed to...and LOVE IT.
Thanks again everyone.
Cole
