Before my wife and I went on our first trip with our old camper I figured a quick check of the wheel bearings was in order as well as a bit of work on the brakes to get them working properly.
The bearings had a nut and lock nut which was adjusted perfectly. Small problem though. The seals had been fitted incorrectly and all the grease was now on the brake shoes and drum. Now that could have been interesting coming down Mt Hotham to Harrietville...
Fast forward about three years and when we got our current camper home I decided to adjust the brakes so they'd work properly and figured a quick squint at the bearings wouldn't hurt while I was at it. Bearings far too tight, and negligible grease in them. The grease was guess where... Soaked into the brake shoes because the seals had been fitted incorrectly.....
