So the rear brake on my GSA went completely soft - all of a sudden - while touring the Rockies with my wife. We were coming down a pass from Breckenridge going south - could have been much worse, not a tough pass. I pulled over and found my rear caliper bleeder screw missing! Just gone....never heard or saw that before. I limped to a buddy's place about 60-miles away. Found a new bleeder at NAPA on back on the road. Have had 6K, 12K, 18K services completed - I don't think brakes are bled until 24K? So was it loose from the Motherland? By the way, northern NM and south central CO was green beyond my wildest dreams.
