This is exactly why we never recommend simply adding grease to trailer bearings.
During a proper bearing repack, we clean out all old grease, inspect the bearings and races for wear or damage, then repack with the correct amount of fresh grease, enough to last until the next recommended service interval (typically every 10,000 km).
A lot of people think more grease is better, but that's not the case. The easiest comparison is an oil change on your vehicle, you wouldn't just keep adding new oil on top of the old oil without draining it first. Bearings work the same way.
When excess grease is continually pumped in, pressure builds up and can blow out the rear bearing seal, allowing grease to coat the brake assemblies like shown here. Once that happens, brakes are often contaminated beyond repair and require replacement.
In this case, the contamination was severe enough that the safest and most cost-effective repair was a complete replacement of the brake assemblies. We got this customer back on the road with a full new set of backing plates and drums, ensuring they can enjoy a safe and worry-free camping season.
Routine bearing service is about much more than just adding grease. it's about inspection, cleaning, preventative maintenance, and making sure your trailer is safe on the road.
