Kaleb took that car (via trailer) to get the wheels aligned and I noticed we have a terrible vacuum leak at the master cylinder as it mounts to the booster. I have the large, square O-ring in there. I noticed when I installed the MC that is never pulled in close to the booster and left a gap. I thought well I have the seal in place, maybe that's the way it supposed to be. I cannot tighten down the MC mounting bolts anymore, they are bottomed out. I can't imagine having to put two seals in place. Both the MC and the boost are new. There is no doubt that is were it's leaking from. Could it be a wrong model of booster/MC? Any ideas?
