Matt why would you wait another 2000 km to take it to the garage and have the brake fluid level checked ? You obviously know how to open the hood, just check the master cylinder level yourself ,on the 2000 Sunfire you can see the fluid level thru the cylinder it even has MAX and Min levels so that you don`t have to take the cap off to look. I`m sure the 2001 are not much different. checking it now for low fluid (possible leak) could possibly save your butt. not being critical here but ...........
