particulate matter in the clutch fluid

[Daniel Neuman <dneuman@stars.sfsu.edu>]

Hello All,
        I changed out and burped my clutch last night.  In the bottm of the
clutch fluid resivour <sp?> There was tiny little black particles??  I know the
master cylinder is only about a year old  but I have noe idea how old the 
slave is.  What is this stuff?? The inside of the rubber hoses deteriorating?
        After the fluid change and the burping the clucth pedal feels stiffer
and firmer than before.
