Does anyone know what might be wrong. I have a 2008 650 prowler and when braking it makes a loud clattering sound. Originally I thought it was coming from the brakes, but my local dealer did an upgrade on the brakes and replaced the brake pads and rotor. Well the sound is still there and it is quite annoying every time I brake to hear it. I wondered if it was coming from the transmission or something. Anyone experienced this??
