I have a 2009 hayabusa, now should i expect the front wheel to drag slightly or should it spin completely freely with calipers in place. it has new brembo disc's new brembo pads and the calipers have been completely serviced with new seals and new brake fluid.
Front wheel drag

Your wheel should spin free providing your bearings are ok,you may be able to hear a very slight noise if your checking before a ride out.
Best thing to do is go for a ride and not use the front brake then stop (with the back brake) and feel the front discs for heat.
Very slight drag is normal, pads don't tend to retreat far enough to completely clear the discs, (a lot of mechanical advantage = not much travel), a very light brushing contact is okay- it won't spin on as free as say a bicycle wheel..
There should be no pulsing, and absolutely no drag you can feel when trickling around or pushing the bike. Perhaps someone could give a definitive guide to haw long it should spin on when given a decent flick, I'm not happy if I can't get a wheel to spin on a bit.
Did the full service involve cleaning the pistons and rubber greasing the seals?
also make sure there isnt too much fluid in the master cylinder as when hot it can cause the brakes to bind.
Fancy a brew?
