On the yamaha blaster(drum brakes) You have 2 take of the whole tire 2 change the brakes right...when you replace the pads if the brakes are still not workin what else do you do do you need to replace the drum aswell

 

big 10-4, and if they still aren't working you might have to check the adjusters on the drum or the handlebars. Also you might have to adjust the lever on the drum that moves the pads into the inside of the drum. Take it off and move it forward a notch so it gets more throw when you pull the brake lever.
