Brakes clunk at stop? on 2006 Dodge Caravan

The brakes have a loud clunking sound when coming to a stop. I feel it in the pedal too. Never at speed, only 15mph or less when stopping. Two different mechanics have heard it, neither could diagnose it. Any ideas?

i bet it is the abs activating at low speed from a sensor issue. take it to another shop familiar with these types of repairs.

Sounds like wet lining in the rears due to leaking wheel cylinders. HTH Wayne
