Front wheel issue

[Kentish]

Hello all, I noticed whilst I had my bike up on the paddock stands and spun the front wheel it only rotates about one turn? I stripped the calipers put in new seals cleaned all the pistons so they were like new. With the calipers off the wheel spins a lot more freely, the discs are not warped as I hooked up a new pair that I have on another wheel and it still done the same. Am I going mental or its this normal? I get about one whole revolution of the front wheel when I spin it.

Pads are pretty worn I guess. Help me!!
