Eurovan Master Cylinder Replacement Problems

I have recently gone through several master cylinders on my '92
Eurovan.

The original failed in one of the cylinders, giving a long brake pedal.
I got a rebuilt unit from Canadian Tire and that is where my fun
began.

The first replacement failed in a couple of days by leaking from the
master cylinder into the booster. I took it back and was told it was
defective and got a replacement. One week later -same thing with the
replacement.

Figuring that this was not a coincidence, I took it in for a mechanic
to look at it. He couldn't figure out anything so he called a VW
specilialist buddy of his. The story he got was that the rebuilt units
almost always fail in the Eurovan - the seal they use is not up to the
pressure. The solution get a new one from Volkswagen or good used one
from a wrecker.

So be forewarned and save yourself some aggravation if you face the
same job.

I have had very bad luck with rebuilt parts, particularly those
purchased at mass market retailers where price is the #1 issue.
