Question When jacked up, should my wheel spin freely?

Greetings,
While jacked up to swap wheels get an alignment. I noticed when I tried to spin a wheel, it was hard to turn. Not two hands hard but it would NOT continue to move at all when I let go. No freewheel or spin was possible. This was a front wheel but I may have tried it on a rear as well.
i thought this could be a cause for my horrible gas mileage.

Should my wheels be able to spin freely at all after i let go?

They should spin fairly free. At least one or two rotations before stopping, maybe more depending on how hard you spin it. It could be a caliper locking up. Jack up the whole front end and compare both front wheels for resistance. Also check brake pad wear from side to side. It will kill your gas mileage.

If its a caliper thats locking do you replace the caliper or do you just push the brake piston out and install again?

there should be some bearing drag when you spin the wheels.1 to 2 rotations at most when spun by hand as chiken said.

If your calipers are dragging badly, you can hear the pads scraping against the rotor, however, pads are designed to lightly drag on the rotors at all times. This is to keep the rotor surface clear of water when driving in the rain. There are flat springs that do this.

You have to replace the caliper. Typically if its stuck or seized you won't be able to compress the pistons.

Another common source of stuck calipers are seized caliper bolts/pins, which you will want to check for before replacing the whole assembly. The rubber boot that keeps the grease packing on the sliding pins deteriorates over time allowing the grease to dry out and the pins to start rusting which prevents the caliper from sliding freely. It's a cheap fix if that is the problem. Just remove the pins and if they're not bent, clean them off of all the rust, regrease, replace the rubber boots, and reinstall them.

Good to know!
Thanks!

Rubber boots around the pins? You've lost me. I don't remember any rubber boots around the LS brake pins. There is a rubber boot around the drain flush bolt.

He's referring to the rubber boot on the sliding pins for a floating caliper that comes stock on the SC3/4. LS400 calipers are monoblock, so their design doesn't require sliding pins for the caliper to work.

That is correct, here's an image to show what I was referring to, you can see one of the boots at the top right side of this stock SC3/400 caliper in the pic below.

Ok, gottchya. I've had some problems with my LS brakes and thought I missed a step.

Those boots can be purchased at auto parts stores right? Hardware kit?
