Brakes and Flaps...

[scottfromiowa]

I often don't use flaps on take off when flying alone in my '66 M20E.  On a recent flight I went to pump in flaps on short final and pump was loose (no pressure).  Landing uneventful and had braking action on roll-out.  Mechanic pulled belly panel and replaced 0-rings in master.  We really had to work forcing hydraullic fluid into reservoir to get flaps to function...

Here is my question...I have now flown three times following the O-ring replacement and during pre-flight I have had to do a couple of pumps to get pressure...and then the flaps do their normal four stokes to lower full flaps.  Anyone else have this.  I previously had immediate pressure and two strokes to 1/2 flaps four to full.  Thoughts?

Second question...Plan to replace tires and brake pads at annual.  What is involved in doing seals for brake master cylinder?  Where is it/are they (one or two)?  Thanks in advance for the "free" education.  I know the brakes and flaps share the same hydraullic system...Also How big a deal to change brake lines (exposed on gear)  These are OEM and I believe some leaking occuring here...

Scott,

Strange thing, I just gave a response to similar issue on the above "brakes" thread.  Have a look, let me know if it was helpful....

Access to two brake cyllinders and flap pump is available by removing the belly panels under the cabin.

I found the brake lines to be in good condition.  They are mostly metal tubes.  The supply side of the pumps seem to be lower pressure rubber....
