I'm in the process of helping my daughter restore her Granddad's CJ-3B. Safety is my #1 concern so I've started procuring Disk brake conversion parts. If I convert the rear drums to disk (I'd like to as it all needs an overhaul and I dislike drum brakes). The only challenge is getting information on the electric control. Does someone have some info on the power and control needs of the electric emergency/parking brake? Also, Is doing only one side with the parking brake or both sides? (Doing one side could cause some differences in rear brake forces too). I can see a benefit but the cost is more. Otherwise, I'll rebuild the drum brakes :-(
