I have a 2005 Aveo LS Hatchback without ABS and my pedal doesn't hit the floor. This passed April I replaced front rotors along with brake pads, new master cylinder (new, not reman) and brake booster and hose / check valve. I also did brake flush. When you hit the brakes the car will stop on a dime! Even after all of that the pedal does not touch the floor. The brake booster itself has an adjustment that you can adjust the travel of the brake pedal. If you change anything there just keep in mind of the brake light switch or your taillights will stay even when you let go of the brake pedal.
