Help with front brakes

(1/2) > >>

blueoval:
I just installed new front brake pads and a new brake line on the 2000 k5.  They are bled and stop the bike much better.  I rode and broke them in.  They are grabbing and the front wheel is hard to turn by hand when on the stand.  It seems the brake rotor is rubbing up against the caliper (see pic).  Any help and suggestions would be very much appreciated.  Thanks in advance.   

Danger4u2:
I had a problem like that on my CR500 turned out the pins the caliper "floats" on were gummed up.  I removed the caliper and cleaned the holes and the pins.  I put a dab of water proof grease on each pin.  If that's not it I would check that the wheel spacers are not swapped.

I bled the brakes with a vacuum bleeder at the shop my girlfriend works at. I had replaced the front brake line and it needed fluid. I took the m/c new line and caliper with a old rotor to the shop to bleed. It had worn out pads. I got a good hard lever and went home. I reinstalled everything and put on new pads. The brake was locked. I removed a bit of fluid from the m/c. All better. If its not the pins or the spacers, maybe to much brake fluid. Best of luck.

KXcam22:
It is possible to get too much fluid in there when using a vac/press bleed.  Never experienced in on a M/C but on mountain bikes it can make the pads drag.  Yours looks more like what Danger said with the lside pins being gummed up.  Cam.

Blue,
 The pins should be nice and smooth also.  They tend to get a groove worn in them if they are not serviced once in a while.
