Rear wheel locked

Got in my 2002 explorer 4x4 last 2 days in morning and
the passenger rear wheel locked and dragged in reverse and
forward for a couple feet on my gravel driveway. It immedately
freed up and had no problems both days after that.

Any ideas what could cause that?

Thanks

No don't use the parking brake. It also doesn't do it in the afternoon when
coming home. But that is on blacktop and may not notice it.

Thanks

Probably your parking brake shoes. It has a seperate drum-type system specifically for the parking brakes.

What happens is the shoes start to separate from their brackets due to moisture getting behind the material and rusting, causing it to push against the drum surface (interior of the brake disc).. when you drive it breaks loose and settles and then it's fine for awhile.

Another possibility is rotor rusting. These are prone to excessive rust buildup on the disc surface and can kind of "glue" the pad in place until vibration and force breaks it loose... then the surface rust is scraped off and you're good again until it's parked for awhile.

I don't recall ever seeing a locked up caliper on one of these, but I guess anything is possible. Good luck
