• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

This is a teaser, for me anyhow!

So, I installed the brake system. New service kits for the Cleveland master and brake cylinders.
Everything works, even the parking brake.
But I have a leak with the left master cylinder.

I have tried all levels of brake fluid in the reservoir. Even at very low level, the fluid creeps up the piston rod and drips down the side of the cylinder.
There is no using the brake, just left overnight and the fluid travels up and out!
Has anyone had this problem in the past? Does anyone have a schematic drawing of the components they can post? Maybe I re-constructed this incorrectly.
Below, some pictures to show the problem.

Thanks. Eric.
