[urq] RE : Brake Master Cylinder Source

[Louis-Alain Richard]

>From my understanding, 857 611 019 is a steel MC where the 443 611 021 is
aluminium. I believe they are interchangeable.

BTW Franck, 443 611 021 is the ATE one I bought locally for 128$CAN. ATE
part number is 010194, or 03.2123-8512.3, according to the ATE web catalogue
found here
(http://www.conti-online.com/generator/www/com/en/ate/ate/general/home/index
_en.html).
