Looking for any assistance in the procedure to replace the brake pads on by sons baja 50. This unit has the brake drum system, and not the disc like on the new atv.

I have looked over the drum very thoroughly, but can't figure out how to get it off so that I can replace the pads.

I have looked over the bajamotorsports.net site, and they no longer have the manual or diagram on the site for the older model.

Any help would be greatly appreaciated. He is driving me nuts to get back on his ATV.
