Not necessarily. The first thing a leaking grease seal on electric brakes (drum type) is reduce or nearly eliminate braking for that wheel. And you may or may not notice that.
I'm doing the yearly inspection on our 2014 Columbus 365RL now and found the left front seal has been leaking, reducing or eliminating braking on that wheel and there was no external evidence. The only symptom we had was some pulsing / bucking under heavy braking (and I really only noticed it over the last two trips (about 2,000 miles).
The point is, that the manufacturer recommends a yearly inspection and I follow that. The first one showed no issues. This second one showed two so far. The leaking brake seal and excessive calcium deposits in the water heater.
The water heater I figured out when I flushed it, then inspected it with an inspection camera (Harbor Freight Cen-Tech - Item#61839) and saw all the calcium chunks and flakes in there. Repeated flushing did NOT remove it. But fabricating a bent tube and attaching it to a wet vac did. Took about 30 minutes to completely flush and clean the water heater and install a new anode rod.
I believe in the old adage, "If you want it done right, do it yourself."
