[Vwdiesel] Ok, let's try another: Brake master cylinder leaking

[LBaird119 at aol.com]

I've been "without brakes" on the pickup for a few months  now.   It stops, 
just not well. 
 The 50K mile, master cylinder started leaking around the reservoir  
grommets late last year.  It got worse, a wheel cylinder started leaking  badly so 
I replaced both to get rid of the leaks and better brakes back.  
  Rebuilt mc leaked in the same place, worse.  Grommets were  really sloppy 
in the holes.  Got another, better but the same.  Found  a good price on a 
new mc (Cardone)  it was better but still leaks, same  place.  Yes I checked 
if the reservoir was cracked.  It's stressing  from being removed so much 
but no cracks, held pressure (by mouth).  I even  put a single wrap of 
electrical tape around the necks of the tubes going into  the grommets.  Still 
leaks.
  The only suggestion I've had so far is to heat and stretch the tubes  
back out, with a blunt tube or rod, just a bit larger.  I'd just replace it  
but I found one place that had them for $89!!  Kinda steep for a piece of  
plastic, to see if it's the problem or another sloppy grommet.  These still  
don't fit TIGHT in the bores.) 
  Anybody else had similar problems or a good suggestion?
  Oh, yeah, It's the Bendix mc rather than the ATE, which everyone's  now 
calling "ah-tay" (sounds like Buckwheat's gone into the parts  business!)  
Bendix is  way harder to find and higher priced, of  course.
