Bleeding the brake with the caliper horizontal didn't help.  However, I
now have a new problem, the nose gear is not retracting enough to close
the doors.  The sag is about 1/2 " and the gear can be pulled up easily
by hand.  I haven't changed anything since I last retracted the gear.
Brendan suggested that the pressure switch may be cutting off too soon.
I turned the hi pressure screws in 1 1/2 turns, 1/4 turn at a time with
no change.  I also seem to recall that years ago when checking the
system with a pressure gage, the adjustments didn't work.  Perhaps Al
Gietzen found the same thing.  Does anyone have a suggestion?  I had
planned to fly to Copper State, now Xmas is in doubt.

I'd say one thing is for sure; it is not a problem with the pressure
switches.  The std setting on the up switch is 1050 psi which is about
800 more than is needed to raise the nose gear, and about 600 more than
needed to tuck away the mains.  At least that is what I found on my
installation.

 

I found that the adjustment screws on the pressure switches adjust the
band with; not the pressure setting.
