Brake Failure - One Wheel. Cause????
I recently noticed a grinding sound from my trailer wheels, so I had my brakes inspected and serviced at my purchase dealer in ABQ. These are non-self adjusting brakes on our 2011 FC23FB. It had been just over 7000 mi since the last brake service by a local RV dealer in Durango. Inspection revealed that one of the brakes had been engaged without activation by the controller, or perhaps stuck engaged after activation. The pad was completely worn and the hub scored. My dealer replaced the entire assembly. The other three were fine with little wear. Cause? My dealer theorized about some foreign object. The controller tested ok. The tire, an original 14" Goodyear Marathon had worn to 3/32" tread depth, whereas the other three were at 7/32" after 15,400 miles. Apparently that brake had been dragging for some time.
Kudos to the GYM tire, as it had worn but not failed even when a good many of those brake dragging miles likely occurred during the extreme heat of the summer down along the Gulf Coast.
So how common is this? What might the cause have been? How might I have detected it sooner?
