2004 Cavalier brake caliper removal

Ok this isn’t really an “Oh crap” situation. I am at work and I have to do my fiance’s brakes when I get home. I just did my sister’s brakes on her 2000 Cavalier and I needed like a 3/8 nut driver or something like that. I can’t remember the size.

Anyway, my dad took the driver with him that day and now I don’t have one. Does anyone know if the brakes are the same on the 2004 or have they changed? I know a few things changed from 2000-2004 and I don’t know if that was one of them.

suspension is the same from 95-2004 so ill assume the brakes havent changed either. im guessin though, research it on jbody.org
