The general consensus is: skip the 23mm+ brake master. Noted. I have seen a number of passing references to a VW brake master (22mm) that is said to bolt in without issue. Based on my research, the VW part number is: ATE 357611019. For those in the know, is this number correct? I have also read that a 22mm from Mercedes will work--I'm open to this option as well.
Any feedback on the intended upgrade would be appreciated, though I am aware of the increased pedal effort and am not concerned . . . unless those in the know say I should be.
TIA.
