One of the tasks I needed to do for the Cessna Annual was pull the brake master cylinders and overhaul them. This sounds like a simple task - NOT. What you have to do is completely disassemble everything around the rudder pedals. This is not much fun in a couple places. In particular, the bottom fitting on the master cylinder is secured with a cotter pin. No big deal except that it is crammed down inside a bracket making access impossible. The only remedy was to take the stupid bolts out and remove the brackets. So that is what I did. This photo is before the final disassembly.
Actually there is no corrosion. The goop on the culinders is dried up brake fluid. You have to remember that most of the structure is aluminum. The torque tubes are steel, but the discoloration which looks like rust is actually just surface discoloration. For a 57 year old machine, it is in excellent shape.
John, to my self confessed untrained eye. This scene gives me the impression of being quite an old object (plane). There appears to be a lot of corrosion and general wear about.
I do hope this is 100% safe to fly. Irrespective of being legal or not.
