[V8] well lets beat this brake acumulator to death again

[Charles Wurts]

You are jogging my memory.  I was faced with a nearly trashed front 
seal a few weeks ago.....  The favorite local techs took care of it for 
me in shortish order.  I was initially told that the first replacement 
pump was bad, so another one had to be ordered.....

Later, in a casual conversation with my favorite local guys, they 
admitted that the "junk floating around in the system" had in fact 
clogged and compromised the new pump.  They only realized it while 
doing the second replacement.  So it sounds like the first replacement 
pump was probably good, but was severely slowed by the junk.  FWIW.
