That's probably what I should have done. Well I Set the park brake and popped the hood. But instead of thinking electrical I thought fuel or air. Actually I picked air and covered the intake (air cleaner was off). It stopped nicely. What I didn't know at the time was it sucked brakefliud back through the system. I found this out because when I adjusted the safety neutral switch I pushed the brake pedal out of the way and it went to the floor. I checked the master cylinder to find it empty. No puddles on the driveway! All in the intake! I started the engine (with my new key) and smoke filled the street. Now I have to bleed the brakes. That's OK because I have to swap out a faulty pressure switch (just have to buy more brake fluid than I planned). Next time I'll pull the coil Dan.

I hate to say, but you have bigger problems than that.

Your booster shouldn't leak and neither should your M/C. Choking off air may have boosted your vacuum, but it should NEVER cause your brake fluid to pass.

Upon further investigation, you may notice that your booster has quite a bit of brake fluid inside. Have you noticed your fluid going down with no apparent signs of a leak? That's why.

I strongly urge you to get another OEM key switch. You can use the tumbler out of the old one to keep the keys the same.

Thanks Dave. Good advice.
Today I bypassed the "Cadillac Bendix Vacuum Booster" (actually I took the whole thing out and plugged up the vacuum tube from the intake.

I bled the brakes and gave it a test run now I have "no" boost brakes and they seem to be exactually the same as before. So The Caddy booster was not working at all !!!

Maybe I'll do the disk brake thing one day if I can piece together everything that needs to be done. Id like to drive a tbird that has all drum boost to see how it works.

Part of me really wants to stay original though.

So anyway the beast is back on the road. Brakes works. Brake lights work (installed a new hydraulic switch) and she starts with a key!
