  1. Could someone please post a pic of their 240z brake check valve? I can’t locate mine maybe it doesn’t exist My running, almost rust free 1973 240z scraed me a bit on my first drive yesterday. The brakes are horrible. Feels like when I botched a bleeding on my wife’s brakes years back. Lots of pedal effort with just gradual slowing. Applying brake while idling causes an increase in RPM. A squishing airish sound when the brakes are first applied. I was originally thinking it was definitely the booster. Then I started to wonder about the check valve. I can’t even find the check valve. I assume it’s on the vacuum line somewhere between the brake booster and the engine. Assistance would be greatly appreciated.
