Hi,
-8, Matco masters and Cleveland calipers. I know about the check-valve. Same both sides.
At home before moving my RV-8 to the airport, I had the brakes bled and a firm pedal (pumped fluid up from the calipers). At the airport a year later I cannot get pressure build up at all even though I can see no air bubbles in the clear reservoir lines. I do have the tail up on a stand and the fuse level.
Is it possible to have an air leak without any fluid leaks? Could stuck caliper pistons be the issue (really, both?) ? Should I be tail down? Might I need to pull and rebuild the masters if they can leak air and not fluid?
Looking for the Occam's razor solution here even if it's the most labor intensive.
I was hoping to upgrade the insurance to "in motion" and do the first start and fuel flow test (and taxi) before snow flies. But not without brakes.
Thanks for any advice.
