My daily rider a 2007 GL1800 Goldwing had a master cylinder recall issued. This was a significant case as the rear wheel would lock and seize while at higher temperatures.
Since the sled was getting serviced and the wheels would be off I had the shop install new brake pads (I thought all three sets) but it turned out to be the left front and rear. I also had the oil and oil filter changed. This all happened approximately at 39,500 miles.
