Not that expensive to replace the complete assembly. For superior braking I recommend going to disks.
$2K+ parts plus labor for disc conversion..
Look, the drums obviously worked well for the OP in the past, with a little detective work and not much more than $250 the OP can rebuild their existing drum system to work just as well as it did when new.
Unless the OP was having brake fade as an issue (which does not seem to be the case) how about sticking with troubleshooting the OPs existing system without needlessly throwing out the baby in the bath water?
Troubleshooting electric brakes is extremely easy and low cost to do, replacing with discs is not easy nor cheap and can introduce a few unwanted side effects like possible incompatibility with the OPs existing brake controller..
