First of all, welcome to iRV2.com. We're glad you found us.
If you determine that your problem is mechanical and you have Dexter axles, I'd see if a replacement brake assembly is available from a vendor such as Southwest Wheel
. These replacement assemblies contain the backing plate, shoes, springs, magnet, bearings, seals, hub, brake drum, etc. and are relatively inexpensive. Going this route, if it works for you, can save a lot of time and worry.
