Brake Moan

["Al Powell" <APOWELL@agcom.tamu.edu>]

Here's one for you folks.  My '90 200T doesn't have a problem with 
brakes squealing - but when backing up slowly, the left rear brake 
MOANS (woooOOOOOOOooo) in a fairly deep register, perhaps about 700 
Hz.  What I think it is - is a pair of pads vibrating on the rotor.  
But it only happens when backing up s-l-o-w-l-y and easily.

I've tried popping one mounting bolt loose and adding hi-temp pad 
lube between each pad and the caliper contact surface, but it only 
moderated for a day or two - and never disappeared.

One more comment - these are original rear brake pads at about 63K, 
so they're about gone.  

Any comments about other things to try?  It's not hurting anything. 
so I can live with it, but it would also be nice to stop....

TIA, colleagues.
