Front brake (area) 'clicks' when braking

["James_ TR6" <jattr6@hotmail.com>]

hmmm...
i have noticed a strange CLICK when braking.
comes from the front drivers (left side) wheel and only
if the brakes are applied hard, like during a full stop as opposed
to slowing on a hill.
i haven't looked yet, but the click may be the brake pads shifting
or the dreaded caliper. i rebuilt the calipers (FYI) years and years ago.

hmmm...any thoughts?

Thanks!
