Hey Sunrise farms congrats on the 208,that is a really nice machine.The brakes are a sore point ,rarely do they work properly.In order to get the brake drum off you will probally have to back the shoes off,the shoes usually wear a groove in the drum and makes it impossible to get it apart.There are nuts on the backing plate which work as a cam system to move the shoes out against the drum for adjustment,release those and you drum should come off.Check to see if there is any oil on the shoes,if so replace the oil seal.If the shoes are not sticking upon operation then I think your problem may be in your master cylinder or a kinked line.Good luck.
