I was blatting along - just overtook a couple of cars next thing I know the front brake lever dissapears.
Pulled over - no doubt much to the amusement of the cars that I had just overtaken, turned around and found the brake lever in the middle of the road.
Now here is the weired thing the pin that holds the lever in was still in place, so I guessed that the casting must have broken - nope.
The pin is held in with a circlip which had come off allowing the pin to jiggle up enough to allow the brake lever to jetsion.
Pulled out the pin, put the lever back in and put the pin in - kept my hand on the lever for the next 20 or so miles home.
Kept thinking what are the chances of the pin moving enough to let the lever come out and then falling back into the hole in the casting on the brake housing - totally bizarre.
I'll have to source a new circlip, no doubt a genuine HD one would be stupidly expensive.
Brake lever now has some road rash in a very strange to remind me of the day the lever "jumped off the bike"
I blame the heat.......
