Vacuum pump is a device which gets the drive from engine cam shaft. In some designs, it is driven by the alternator shaft. The main function of vacuum pump is to evacuate the air from the brake booster tank, thus creating vacuum, which can be used for brake application.
When the pump begins to fail, it produces less suction which helps to provide pressure to the brake master cylinder and provides additional pressure inside the brake lines. Eventually the lack of pressure in the brake system works its way up to the pedal.
