SURVIVOR
Annie and I went for a ride today. 60 sunny degrees in Montana and just a beautiful day to ride. After riding about 110 miles we stopped for coffee. When we came back to the bikes, eagle eyed Annie noticed a 2 inch in diameter puddle of fluid under the left front caliper of her 2014 F800GS. I glanced and was about to dismiss it as an old puddle, but took a closer look and sure enough there was a stream of brake fluid running from the bleeder. The dust cover was gone from the bleeder and a very small amount of fluid would come out the bleed hole when the brake lever was squeezed. There was no evidence of any brake fluid on any other part of the bike. Nothing on the rim, tire or engine as would be expected if it had been leaking while she was moving. The reservoir looked full. Although the puddle was 2 inches across, a little brake fluid goes a long way. The bike has speed bleeders that I installed when it was new last September and about 9000 miles ago. I used a wrench and was able to turn the bleeder about 1/16th of a turn, if that much and the leak stopped. It was baffling. The leak seemed to start suddenly while the bike was parked, the dust cover was gone and that is not something that happens easily. I thought of the idea that someone had purposely loosened the bleeder in the parking lot, but that seemed unlikely and too insidious to consider happening in small town Montana. The conclusion I arrived at is that the bleeder has been leaking a minute amount of fluid for quite sometime; perhaps for the last 9000 miles. Every time Annie used her brake a small amount of fluid was fed under the dust cap and eventually the fluid jacked the cap up until it came of the bleeder. It probably came off as she was braking to stop at the coffee joint allowing the trapped fluid to run down the caliper and puddle beneath the bike. It was another 70 miles home and there was no evidence of any additional leaking.
That's my story and I'm sticking with it. I guess I did not get the speed bleeder tight when I installed it last year. Any other ideas?
