We have a 71 ECA with heel brakes. The left brake got soft last fall so, suspecting a lack of fluid, and taking the lazy man's way out, I disconnected the line at the top of the master cylinder just behind the brake pedal, and filled it up. It worked thru the rest of the fall and what little we flew last winter. Ditto for the first few flights of the spring. The pedal got soft again, so I repeated the procedure yesterday. I re-assembled the fitting, and still not up to par, so I took it back apart, and squirted a bit more in.
While the fitting was still open, I had someone push gently on the pedal while I was looking underneath. There are what appear to be two 'overflow'? tubes (1/16" copper) that exit near the centerline of the fuselage, and the fluid was coming out of the left one.
I did not try the test again after I re-assembled the fitting....duh.
Anybody got an idea what's going on? I've got the maintenance/parts manuals and will dig them out later today. Thanks!
