Looking for someone who can time vanos

I found one vacuum leak in the hose that goes to the brake booster. I removed the OEM clamp and put a new on on. It still misses so I’ll check it again, for leaks, tomorrow morning. I put some cardboard under the car. It appears the slave cylinder is shot. The brake fluid is dripping off of the bottom of the transmission. Should the brake pressure be enough to pop the seal on it?
