i put windshield fluid in the brake fluid place.

Did you drive after putting in the fluid or notice it right away. The brake fluid is a hydraulic fluid and WWF is not. If the wwf just say on top of the brake fluid and you were able to remove most/all of it then you "should" be ok. If you drove the car and used your brakes then I think you will need to purge the entire brake system and then fill it back up with the proper brake fluid. You will also need to bleed the system to make certain there is no air in any of the lines/system.
