Re: k6 600 rear brake problem
Do you mean the movement is stiff or that there is only 1/2" of travel before brake application?
I just checked my two bikes and both are just at 1/2" travel before braking with a firm pedal. I suspect you had air in the system previously and just did a good job bleeding it out.
If you meant that the movement is stiff, try squirting some oil on the footrest pivot. Also, if the bike has been dropped or crashed, the rear peg could be slightly bent and binding the pivot.
Some guys that track their bikes, and want a little less rear brake sensitivity and power, will actually introduce a little air into the system to "dumb it down".
I lowered my brake pedal a little and that also seemed to make it more user friendly. (Doesn't change the brakes but helps with the bio-mechanics?)
