So I just finished putting new rotors on my car, however, when I assembled everything back together, there seems to be quite a bit of resistance when I try to turn it. Is it supposed to rotate freely or should have I reset the calipers even though I didn't replace the pads? Thanks.

Yeh, when the caliper is off the car, open the brake filler reservior cap. Then take some brake fliud out of the reservior.

Now force the caliper pistons back into the caliper. Preferrably use a threaded brake tool for this. Be careful not to pinch the rubber dust caps that surround the pistons.

NOw bolt the caliper back on to the car.

Refill the reservior with fresh fliud. Replace the cap and gently pump the brakes until the pressure builds.

I hope you cleaned and greased the slidder pins.

Thanks. I cleaned pretty much everything and everything seems to be working fine.

For one you should never install new rotors with old brake pads because the pads wear to the rotor and there is no need to take brake fluid out of the reservoir. Only time you need to even open the reservoir is if you are doing a brake flush or beeding the brakes.

^^^ ditto, you sould always use new pads when using new rotors or turning old rotors. you'll get away with reusing older pads sometimes, but using new pads is allways a good idea to avoid hotspots and promote even braking power.
