Front brakes dragging?

Anyone have issues with the front brakes dragging at all times?
I noticed the front wheels were not spinning freely while lifted off the ground. After changing from stock to EBC green pads, they were much more free to rotate, but over the last 3 months, they are dragging again. It is both sides, about the same amount of drag. Fluid has also been changed.
Is it normal caliper action to have this amount of drag? Not only do the wheels not spin freely, it takes deliberate force to rotate the wheels.
Any advice on how to lessen the drag is appreciated.

It's not atypical for brakes to have a little drag. Is the dragging significant enough that it's causing wear to your break pads?

If in doubt....flat out!!!

Pull the pads and take a look at the caliper seals. Probably not retracting properly.

Hard to tell if it is wearing the pads, I would assume so since there is constant friction.
Car has about 25K miles, are these calipers rebuildable and if so when is the recommended interval?

So nobody else has noticed this issue? Mine must be binding for some reason...

What to look for? Would they be twisted or warped in anyway? Otherwise, I assume they would just look even 360 deg around...

This is not normal at all. When I spin my wheel with my hand, I get at least a couple rotations before it stops.

This is happening to both front wheels? It's not normal. Both calipers, I would say maybe you have some hydraulics issue... the fluid isn't returning to the reservoir for some reason. Do you know how to open the bleed valve on your front calipers? If you do, and fluid squirts out without you pushing on the brake pedal, then I think almost for sure you have some problem with your hydraulic system.

What about the rear wheels?

OK, will try bleeding to see if there is residual pressure. Yes both fronts do it.
Rear wheels spin much more freely.
Is there some kind of check valve in the system that might cause pressure buildup?

What happened on your brakes? Mine have done the same thing for a long time.

2006 Elise, Graphite Grey/Red leather, Sport Elise Suspension, Cup airbox, ECU ref lash, MonoBalls, etc. etc.
1992 900SS Ducati Race Spec Built by Ferracci
2006 KTM 950 SuperMoto, a work in progress

Old stuff gone: Ferrari 275GTB/4, '69 1275 Cooper S. '72 500 Fiat, old Jags, etc. Never bought a boring car.

I get some squealing when the pads get hot. Ferrari of Denver claimed it was the rotors were slightly grooved and they are rubbing a bit.
