I changed the front brakes on my F2 this evening. When I push the bike forward I get a squeeking noise, I dont get anything when I move the bike backwards, and after I have come to a stop I get a really loud pulsing squeek for a short distance and then it is fine until I stop again. I checked the rotors and they are straight, and all the pins have been lubed.

 

Problem solved, I don't understand why, but it is. I got the front end in the air this morning and fount the noise to be on the right side only. It sounded almost like someone rubbing a finger on a balloon. I removed the caliper, looked and the pads over. It looked like the pads where only contacting in the center. I took the pad that was on the inside and put it on the outside and the outside pad was put on the inside. The noise is gone and the brakes work fine.
