So having an RV requires maintenance skills that span several disciplines and specialties. The automotive portion include brakes and bearings but to keep things interesting the breaks are drum and electric. We’ve been getting errors about the trailer break system when towing the RV and it is a really annoying repeating beep. And as we’re heading into the mountains (and back down), it seems like a good time to inspect and maintain the braking system and repack the bearings while I had everything apart. While this is my first look at electric trailer brakes, it’s nice that you get two on each side to compare. We’ll be heading to Isle of DuBois tomorrow to shake down everything prior to leaving out.
