Al,

Also check the fill caps on the master cylinders. Sometimes (especially
the plastic ones) they start to leak. (make sure it's not cross threaded)

The other thing to check on the master cylinders is the top part of the
cylinder itself. There is a cap which is the same circumference as the
master cylinder that screws into the main body of the master cylinder.
(It's the part that the fill cap screws into.) If is is leaking here,
you should notice fluid running down the sides of the master cylinder
after flying inverted.

I have had the same problem in the past, and by tightening the main cap
(not the fill cap) on the master cylinder, I was able to solve the
problem. Hopefully you have access panels to the master cylinders,
otherwise you will be standing on your head inside the cockpit to access
them. :-(

Good luck,

BJ

While recently doing some extended inverted time, practicing rolling out on
headings while still trying to maintain altitude, I noted some brake fluid
had leaked onto the pedals and got rather slippery. I hadn't noticed this
before, as most of my stuff so far has been positive Gs. I'm assuming the
fluid is leaking out the vent holes. Has anyone had this happen before, or
do I need to look further at my brake system? Suggestions?

Thanks,
