Tonight, I replaced my bad master cylinder, and a bad wheel cylinder. I went through the bench bleeding process, and I also bled all four wheels. I still have a soft pedal. I did notice a small hole on the bottom of my master cylinder, near the power booster. You can hear it sucking/blowing air when pumping the brakes, It wistles when the car is running. Is this supposed to be open, or should it be plugged? I'm thinking it should be plugged up, If it should, can I just plug it with a bit of blue RTV silicone?

Also, I found out that the brakes had been changed before I got the car - I had to get a master cylinder for a '69 model, because the '71 mc was totally different, from the resivoirs to the piston.

Thanks for any help!
