Squealing sound after sitting overnight

Not sure if anybody else has this issue but when I leave my Pioneer overnight and go to use it the next day there's a squealing sound coming from it as soon as I start moving. Now I've had this noise since this spring and just assumed it was from the e brake pads. I never used the e-brake unless I haul the Pioneer on the trailer.Once I drive it about 100 to 200 feet the noise stops and I never hear it untill I leave it overnight and go to use it again. I've jacked the rear up and put it in gear while its running but of course can't hear the noise then.If I turn the rear wheels by hand [engine off] I can hear a slight squeal coming from the brakes. So just wondering if anyone else has had this happen on there Pioneer.

I kinda figured it must be the back brake.I had pulled it off and turned the rear wheels by hand and there was no noise.When I put the back brake caliper and pads back on there was that slight squeal. So I figured I'd ask if anyone else has this noise after letting it sit overnight.
