[urq] Brake Master Cylinder Source

[fdekat]

Hello All:

I'm thinking that my Master cylnder is not long for this world..

I can press on it at a stop, and it slowly goes down, but no external loss of
fluid.

83.5 urq..

Any thoughs on a replacement?

1) New? I think it may have been  Louis-Alain who had perhaps sourced one
from the original supplier (reasonable $) vs Audi (loads $$$!) Source?

2) Cross over from a different (and more common!) Audi product? Any idea of
what cars use similar?

Thanks!
