I have gotten all the screws off the brake drum but there are to little screws i cannot get off and it looks like an alen wrench fits in there but every-time i try to remove it it starts striping the screw, i tried penetrating oil and heat but it is no use, is there any other way to get those off please message me thanks
Drill them out. Those screws are only used by the factory to prevent a drum from falling off during assembly and are not even sold by GEM. If you need further help getting the drum off, read this http://www.electricforum.com/cars/neighborhood-electric-vehicles-hev/2619-gem-brake-drum-removal.html
