I get a fairly loud clunk from the rear of my 02 Explorer the first few times I step on the brake after the car has been sitting overnight. The clunking gradually diminishes with each tap of the brake and then goes away completely after about the first 20 seconds after startup. Since this goes away after a short time, I'm suspecting a caliper piston is bad. Is anyone familiar with this issue or know how to diagnose it (short of swapping parts)? There's a lot of clunk related issues in the forum, but couldn't find this issue with this model.
Thanks
