83 200E Rear Brakes Help (Pics included)

[Jgrizz]

Hey guys, this is my first time ever ripping out the brakes on any trike and I have some concerns with this one... I opened up the drum and found NOTHING there, which really concerns me that this is more than just a brake pad and done fix...

I included some pics - So far ive ordered the pads and the springs that go between the pads.. Is there anything you see that is wrong or some part that I am missing?

You need a axle bearing kit. Shoes and springs. There is a timing park,,dots,that line up on your brake actuator cam,take your cables off,note the timing marks. Take your cam out ,CLEAN everything,,that's been MUDDED! Shine and grease your cam,reinstall,clean your drum up nice,use silicone around the drum cover going back together,antiseize on the axle splines,and grease or antiseize on the hubs. Tighten the Heii out of your hubs,new cotter keys,Enjoy.
