--- Quote from: hughes ---Hey Guy's. I installed some new rear pads before I rode today and noticed that after I rode the bike and looking at the rear caliper I noticed that the pads relax about .020 off the rotor. The rotor is not warpped. The day before I torn apart the rear master cylinder and cleaned and installed new dot3. Could my rear caliper be binding on the caliper pins not allowing the caliper to float. The pins are not grovved and are not removable. They are attached to a caliper holding plate that $95.00 from kawasaki. Please help if I have missed something.

I noticed last time I had mine apart, there was dirt in the hole where the front pin goes.. It had been making made padds run crooked and wore out the top of the pad first..Clean it out (with a drill bit by hand) and has worked fine ever since..

hughes:
Guy's I also noticed now that I got the rear wheel and caliper off and looking at kawasaki online parts I am missing two pad guide springs for the outboard side pad. Are these that important. They are only $2.00 from bikebandit.com. My rotor looks good but it is know bluish in color from overheat. What casues the rotor to overheat :?: I took emory cloth to the rotor to de-glaze it.

I would have to agree with Brian SM on the Motul brake fluid.  Switching to DOT5 is a hassle and I never found it to be a benefit.  Using high temp DOT4 Like the motul 600 is a better way to go.  At the end of the season my rear motul fluid looks pristine, no discoloration.  Avoid automotive DOT3 stuff as it can't handle the peak temps.  Hope this helps.
