Hi Jim,

You are right, the clanking and rattle of the brakes have always been there 
and I should have explained my problem a little better.  

A week or so ago, the left side brake assembly suddenly had a new sound 
coming from it that was different from the clanking and rattling sounds I and 
you have grown to love.<G>  And upon closer inspection, the brake pads were 
CHATTERING and catching the brake disk during 25% of the rotation.  It just 
didn't sound right.  

Well anyway, I disassembled the brake assemble last Saturday and also 
mentioned the problem to several other pilots on the field.  It turns out 
that my friend Rich had the same problem with his Aerostar and gave be a 
lubricant to use on the cylindrical sliders (don't recall the lubricant 
type/name but will post it as soon as I look it up).  In addition, the 
shorter cylindrical sliders had scuff marks on it.  I carefully sanded the 
sliders with 1,500 grit sand paper and then used metal polish to buff them.  
This removed all the scuff marks and it felt really smooth after this 
procedure.  I then reassembled the thing back together and then put a dab of 
the lubricant on the sliders, carefully making sure that none of the 
lubricant comes into contact with the pads.  Walla!  Chattering is gone, only 
the good old rattle/clanking is present.   Rich mentioned that he puts 
lubricant on the sliders ever time he replaces his brake pads, I will do the 
same from now on...

<< I replace the pads, as you have done, upon the first indication of uneven 
wear which usually occurs with lots of pad left. The last set of pads 
(Cleveland) seem to be wearing much better.>>

Yes, the Clevelands are much better (my original Matco pads, as you may 
recall, all cracked and chipped after a only a few hours and landings).  And 
yes, I don't skimp on the brake pad replacement also.  It is easy and cheap 
enough to replace.  Good insurance for such a critical component of this 
aircraft...  

See you at OSH...

Rick Argente
