Re: Hard pedal, no boost - good vacuum, good servo, good MC.
Thanks guys, but that's not it.
I checked two different boosters, one of them is brand new, and works just fine in another car. Two different valves, both working good in another car. That has to be something else.
On second thought, pedal isn't actually hard from the top. It gets to about half of distance, and then stops rock hard. So it actually behaves something like in the car without booster at all while engine is running.
Pumping with engine off makes it hard, starting engine makes it go down to half of distance.
Could it be something with proportion valve? I'm out of ideas, and almost ready to rebuild breaks from scratch... Problem is I do have access to some spare parts, but not all of them (proportion valve being one of them) and it takes almost two weeks to get them to Poland. If I order something, which I'm not sure that will help, I may end up with wasting two weeks, and double price for that part (if you add shipping, and customs it's something like double price).
