Cadillac Repair: lost brake booster, cadillac sedan deville, power brakes

Question
have 1989 cadillac sedan deville w/power brakes , abs. ac.
have 4.5liter engine. I was driving and everything was normal but the next time I steped on the brake pedal there was no power assist. I can not find the power booster, and that is the only thing I can think that could have caused this. would appreciate it if you have any help,
thanks

Answer
IS or HAS the ANTI-LOCK brake light ever appeared on the dash ?.

If it has and you can't find that big round brake booster then you have the TEVES system brake syatem which is a pain in the A-- to fix.

There is a special sequence that you must follow in the trunk at the brake module to check for codes.
