The rear brakes on a Honda are seldom good for long .. you will run out of adjustment long before the linings are worn much .. If mud/water get inside the drum it will wear the drum ,then even new brake shoes won't have much adjustment ..
If the brake drum is worn you can move the brake arm 1 or 2 splines on the cam to get a little more life out of the drum .. Don't move it to much or the cam will go to center or over center and the brakes won't release when you let off the brakes ..
To keep water out make sure the brake panel bearing is good and keep lots of grease on the axle seal & seal the drum cover to keep dirt & water out ..
The parking brake cable will stretch a little if used a lot .. The older TRX's had a cable adjustment at the lever which helped the hand brake last longer ,but Honda stopped using that type of handle for some reason ..
