Brake drag
How free should the front wheels spin, when up on a jack . Mine will stop the second I let go of them , and seem to have alot of drag to them. The brakes where done 5000 mile ago and one had a new caliper installed.

One is a little worst it will spin around a half of a revolution after I let go. I was thinking slide pins may be sticking, I lifted the rubber boots on both of them and stuck the tubing attachment and sprayed some WD40 on the slide pins they looked clean and shiny at the very end that I could see.

I found this to be a common problem on my old Bronco. I'm guessing it may be the same cause here. The flex lines. They swell internally and don't release the pressure on the pads. You can't see the problem from the outside. Disconnect the flex line from the caliper and see if the drag goes away. Good luck.

FYI You can use a "C" clamp to puch the pistons back into the caliper a small bit once you remove the caliper to make putting it back on a little easier.

Just had the main break line running along the frame behind the fuel tank to the back brakes replaced about a month ago and at that time they flushed the brake system, the rear brakes were redone with new pads and calipers 2000 miles ago and the front was done 5000 miles ago with new pads and one new caliper, the one on the front that has the major drag is the one with the old caliper, so its probally the slides.

Biggziff explained it well. I'll just add that if you crack open the bleed screw it should relieve any pressure too. That way you wouldn't need to disconnect the flex line or bleed the system. It may not be very common, but in 20 years of owning a Bronco I changed the left side twice and the right once for this issue.
