I'm having an ongoing issue with my front brake and need some advice. Whin I fist purchased my '02 Superglide it felt like the front rotor was warped. I felt a slight pulse in the lever under hard braking. I replaced the rotor with an HD floating rotor and the pulsing went away. After some riding I noticed a chirping noise coming from the brake. It never made any noises when the brake was applied. Only when the brake was off and riding at low speeds or when pushing the bike with the motor off. The problem was more noticable when the brakes were hot. I then decided to change the pads and see if that would help. When I removed the pads I noticed some slighly uneven wear on them. I replaced the pads and for a while the problem went away but it has returned again. I took the pads out again a looked at the rotor really well. I observed that there is additonal wear on the outside half of the outside pad. Only half the pad appears to have the additional wear and the inside pad is fine. any ideas? Do I need to rebuild the caliper?
