2002 Dodge Caravan brake question

The front brake is squeaking but only when I don't have my foot on the brake. I have never heard of this before as usually brakes squeak when the pedal is depressed.
Any ideas?
Thank you.
Chuck

How many miles on the van (or since last brake job)? Could be time for new front pads.

the wear indicator on the pad typically makes a noise when the pad is worn out and its often noticeable when you are not using the brake.

I have 05 RAM, which is not that far from your Durango. My brakes squeal like hell, but only when gently touched and barely rolling. Slightest stronger pressure on brake pedal makes it go away.
Chuck, brake pads never really go away from rotor. They are gently bumped away from rotor when hydraulic pressure is released but, gap is very minor and they do brush on rotor ever so slightly.
I'd start with looking at rotor surface. If it is glazed, as in - almost mirror shiny, that WILL cause squeal. Cheap rotors do that. Now, if your pads did same, as in - built metal layer onto themselves and it caked in and is also shiny - that is a double whammy.
Needs to be taken apart and inspected.

Some ideas given the facts you presented (recent pads/rotors):

Given your mileage, it is possible the caliper itself is worn, that is the part of the casting where the "ears" of the pads move ever so slightly on each time you brake. Many shops grease this, I prefer an antiseize compound which tends to avoid wash out. If the casting is worn, the pad might have a high frequency vibration which would sound like a squeel. You might take a look and see if this area of movement looks dry and/or corroded, which could also hang up the pad and cause squeel. Relubricating with antiseize might solve for this, or a new caliper. If you had calipers replaced, with a rebuilt rather than new item which is often the preference for costs, the casting on a rebuilt item might not be as tight a spec as it should be. Not all rebuilders are meticulous with the castings they reuse.

It could be a worn wheel bearing causing some runout which when the brake is applied would line things up and stop the squeel. Might have the car jacked and rock the wheel a bit and see if there is any play, and spin the wheel and see if you can get a visual on a runout. Probably not the cause, but the symptom you describe is odd so some more remote possibilites makes sense to think about.

More obvious things can be the metal brake disc shield gets bent and rubs the disc, but this would not typically go away on braking, but maybe the small movement of the caliper clearances the shield when the brake is depressed. Loose or broken stainless steel pad retaining clips would be another things to inspect.

And of course is could be the caliper and/or piston is sticking, and one of the pads is hung up and not returning fully on release of the brake. Need to look for uneven wear on the inner and outpads as a sign that your caliper is not releasing fully. Sometimes caused the by the slider pins needing grease, easy to remedy. If piston is sticking, then a caliper rebuild is required.

A good inspection should uncover this one without too much fuss, might well be something trivial.

Curious how this works out for you!
