While in a drive through i was creeping up and when trying to come to a stop my brake pedal would not depress all the way as normal and took a longer than normal time to stop even with both feet pushing on the brake pedal. I ended up rolling into the car in front of me. I took the car to the dealership the next day and was told that my vacuum pump/brake booster needed to be replaced.
