You probably have a problem with your brake booster or the vacuum line to the brake booster. The brake booster is a vacuum driven device that helps pull the brake pedal down according to the amount of pressure you put on it. When it develops a leak you get what you are experiencing. Contact YourMechanic to have a technician come out to your home or office to check out you brake booster for you and let you know what it will take to fix things.
