i have the same thing happening. it's not really "clinging" more like a "click" or slight crunch.
it feels as if it's under the car, near the gas and clutch pedal. it happens occasionally, but like said above, only when braking, slowing down, and stopping.
you feel it through your feet, at first i thought the floor mat wasn't on right, but that wasn't it. i have no idea what is the problem.
