  1. Brakes pulls fluid from lower in the reservoir than the flaps, right? Fortunately, have not had any issues with the brakes themselves but a good idea to give them a good look over. Hoping it doesn't turn into a guessing game.
  2. Picked up a M20G late last year and have been loving ownership so far. Lurked on here for a good while prior to finding the one for me--reading about the planes, potential issues, ect--so thank you to everyone for the plethora of information. But it is plane ownership so something has to go wrong eventually, right? A month or two after pick up, the flaps slowly stopped working, going from sometimes getting half deployment to nothing at all with a springy handle. In reading all of the other threads on the topic, it seemed like a leak somewhere in the system so I topped off the reservoir, pumped the flaps a million times and eventually got full deployment back. Red fluid drips on the belly confirmed a leak. Over the next two months, the same cycle happened 2 or 3 times, flaps would stop working, top it off, pump a million times, flaps start working. Finally got a temperate day to spend some time poking around the belly panels and took a look at the pump to see a hydraulic fluid drip up on it, so got on a mechanic's schedule to have him take a look. He wasn't convinced that the pump was leaking enough to force me to top off once or twice a month but he inspected the rest of the hydraulics and couldn't find anything obvious so I had him overhaul the pump since it was our only lead so to speak. Flew her home with working flaps. Then had to wait a few weeks due to winter weather before getting to fly again and lo and behold, no flaps again. Topped off the reservoir, pumped a million times and got pressure back in the handle but the flaps don't move at all (they move when you push on them outside). Eventually, after a lot of pumping and attempting to cycle the pressure from the handle dropped off and returned to the spring back state which I assume is a vacuum in the pump based on all of the other threads that I read through. Crawled around under the plane taking a look at various panels to see if there was anything new or obvious but the pump was perfectly clean and no fluid below it. Looked at the actuator, didn't see any issues or apparently leaks there either. Log books only mention one hose being replaced sometime in the last ten years but all of them look fairly new or they don't fit the hard and bubbly description I've read on here. I guess at this point the only other option would be the actuator considering that's the last piece that hasn't been touched in the last decade (or at least I couldn't find any mention of it in the log books). When the flaps did work, they were solid, no slow leak up, handle stayed put and at time of purchase was 4.5 pumps to full flaps, great timing in the air and on the ground, just couldn't contain the hydraulic fluid apparently. Anyway, going to take a look with him in a week or two if schedules line up, figured I should get ahead of it and see if anyone had thoughts on it or had recommendations on what to take a peek at. Appreciate it in advance.
