Subject: Re: [LML] Bill Maddox speed brake repair
Content-Type: text/plain; charset="us-ascii" ; format="flowed"

I have the Bill Maddox speed brakes, and once I started flying after 
they sat for years waiting, they were slow to retract under the force 
of wind over the wing.  He advise to "burn in the clutch" meaning run 
them up and keep the button pressed, run them down and keep the 
switch pressed, until the oil on the disc and the clutch get a bit 
more grabby.  He recommended an hour of this, but a half hour of 
continuous (gruelingly boring) running seemed effective.

But my problem was only their disinterest in coming down when 
commanded during flight speeds over 150 KIAS.
