sizzling rear rotors again

[james accordino]

I've never replaced a pin.  If the pin/bore in the
carrier are so bad they can't be cleaned, I go to the
pick'n'pull.  Doesn't take long to find a nice one
that can be cleaned and regreased.  As for the kits,
I'm beginning to suspect there's ONE kit that fits
like every Audi and VW from our vintage?  I bought
several sets a few years ago when I realized what a
problem this was.  Still have a few and am looking at
one right now.  Green Lucas box with white lettering.
Have gotten a few in yellow Lucas boxes with blue
lettering.  Earlier color scheme?  Audi p/n 443 698
470.  Lucas p/n SP7250.  Made in Germany.  Also says
Girling on that label.  4 pin boots and small packet
of red grease.  FWIW, while grabbing this box off the
shelf, I saw some other items.  Open box of G60
rebuild kit.  Open box of rear caliper rebuild kit.
What's this book?  5 page technical paper with "9"
photos, including an excellent exploded view.  Didn't
even realize this was in there.  Lucas publication
#XZB137.  They mention Piston Repair Kit (piston boot
and o-ring)?, Hydraulic Overhaul Kit (all the
seals/o-rings on the brake fluid/hydraulic side of the
caliper)? and Adjuster kit (spring and grease seal for
adjuster cam)?.  Pretty good stuff.
