I had a GREAT weekend working on the cat. My 15 year old son spent the day in the back yard sandblasting and painting the bell housing (it looks great), while my 13 year old son was in the garage carefully pulling the heater core and I was in the driveway removing 40 years worth of grease and dirt off the transmission and painting it. Anyway, on to the topic of this thread: I finished the transmission and then moved on to remove the brake master cylinder. Disconnected the lines and then removed the two nuts holding it to the vacuum booster. Then I tried to remove the master cylinder and it would not clear the shock tower before it reached the end of the studs. So I decided to remove the vacuum booster and master cylinder as a unit. Went under the dash, disconnected the pedal and switch, and removed the 3 nuts that hold on the booster. I then went under the hood and removed the remaining booster bolt and the booster would not budge! Looked at the factory service manual and according to it I did everything right, but the booster still won't move. Anyone have any ideas on what I did wrong or possibly forgot to do? Thanks.
