Re: Brake pedal question
I have not had to perform a booster test on a wk2 but all you really need to be worried about is that you have 3 or so decent assisted pumps after you shut it off before it gets hard...
A way you can test normal operation yourself:
run the engine up to 1500 rpms for a couple seconds, lift your foot off the accelerator pedal, turn the engine off. wait 90 seconds then apply the brakes, you want at least 2 assisted pumps before it gets hard... IF you have 2 there is NOTHING wrong and a trip to the dealer will just tell you what I just told you. The system is not designed for retaining vacuum for nights or days, while it is designed to retain vacuum which in some systems may hold for days, this one does not, doesnt mean anything is wrong, just how it is.
