My 1992 cadillac deville brakes do not work. I shifted from park to drive and the car took off. The brakes were completely locked up. The pedal for the brakes felt like a brick it would not work. I had to shift it into park so it would stop. I have a automatic transmission. I changed my master cylinder and break booster almost one to two months ago. I also can not get my brake drum on the right rear side. Thanks.

2 problems may be related. A big vacuum leak would make booster fail and car rev.
