Not the booster. Likely bad master cylinder. Had same thing happen to me with a brand new car. Left the dealers lot, got to first light and pedal hit floor. It was standard shift so was able to nurse back to dealer without an accident (except in my trousers). gm66

Had a repair shop that I have delt with in the past and was very satisified with their work look at and make the repairs. The master cylinder was replaced as well as the rear shoes and rebuild the rear wheel cylinders . Checked the front discs and they were fine . Brakes were working fine until yesterday...brake pedal went to the floor and the brake lite came on . Good thing this happened in my driveway and not on the road like the last time the brakes failed . Put the car back in the garage and checked the brake fluid level and it fine, about a 1/4" fom the top. The brake job has less then 1000 miles on it. Any ideas went could have happened ? Could it be the vacuum booster? Thanks , Pete Hnat _____________________________________________________________ Netscape. just the net you need
