Explorer front brake scraping WHILE driving...
2000 Explorer 2WD. I had tons of frontend issues that I have been working through. So far I have done upper control arms, upper and lower ball joints, tie rod ends, got an alignment. The steering/suspension system is in good shape now.
Now the only thing left is a scraping/grinding sound coming from the driver's side brakes. I mostly hear it at low speeds (taking off from lights, etc). When I was doing all of the other work, I observed that the rotor is in great shape, brake pads look great. I am wondering if it is a caliper issue, maybe the caliper isn't releasing enough or something.
Thoughts, suggestions on what to check?
Thanks!

I will definitely check it again. Do you think there's any way it could be the backing plate since the sound completely stops once I depress the brakes?

One thing i'm not sure of is how much the caliper is supposed to move at the area where the rubber boot covers the bolt. Seems like mine move too much...

Mine did this because the caliper piston was hyper (over) extended and would not retract enough to keep the pad from dragging slightly. The sound stops when the brake is depressed because it is now applying firm pressure.
Problem with mine was that the front end toe was in way too far and that caused excessive wear on the back edge of the inner pad. I could not see it from the front or bottom when inspecting the break pads. Yet, when I removed the caliper and checked, the very back of the pad was ground down to the metal and was starting to tear up the rotor. I'd pull the calipers and look and at a minimum, check and clean the ruber boots on the piston.

I solved this problem and wanted to post it for any future searchers. this REALLY sounded like it was coming from the front, but on a hunch, I took off the back drivers side wheel to check it out. Turns out there was a piece of metal jammed up behind the rotor and the caliper, scraping terribly when the wheel turned. Luckily, it was inside of the usable part of the rotor, so absolutely no damage was caused.
Just a reminder guys, always keep an open mind and check everything!
