fork chatter?

Ok, so I'm on my steel frame 80's Specialized Sirrus and there appears to be an issue with the front end somewhere. When I'm on the brakes, not super hard or anything, I can actually see the fork moving back and forth at the hub. The wheel itself is true and the braking surfaces are clean, so I'm not sure why this is happening.

Could the head bearings be shot or anything like that? Any ideas?

Hold the bike with the front brake clamped on hard and try to move it forward and backward. If there is any movement of the fork or feeling of play, the headset need to be readjusted. If readjusting it just until the play is gone results in binding, the headset is shot.

Thanks! You hit the nail on the head. I tried the brake trick and it was indeed loose. I had just given the old bike an overhaul last winter, and I apparently failed to torque the headset down properly. This is the first time I've put any proper miles on it and noticed it. I tightened it up and it's riding great now.

Thanks for the help!
