12rafel Posted April 10, 2010 I have a KX250 2 stroke 2005! I did rebuild the master cylinder and the caliper too, I just bleed the line and when everything is ok, I run the motor and when I lock up the brakes. I have to wait several minutes to cool for q destrancarse again. I am using Motul DOT 4 fluid, there will be any chance that this liquid is the explanation of the problem, or have something else to change? Thanks! Share this post Link to post Share on other sites
