Question Rotor & pad contact

Today I removed my front wheels for the first time since I bought my car 3 weeks ago, and gave a good look around.
I was surprised when trying to rotate the rotor, it won't do a full rotation without touching the pads at one point.
Is that the way it's supposed to do?
I did have the hand brake on, but it's only acting on rear wheels right?
Also the brake pads looks pretty new...
Thanks

does the steering wheel shake when you step on the brakes ? you will use a torque wrench on the bolts right ?

You should be able to spin the rotor freely with the wheels off (and handbrake off if it's the rear).

Does it always stop or rub at one spot?

yes hand brake works on rears only. Soudns liek your front...

...rotors have a slight warp which means that they contact the pads at one location as they spin. Ber in mind nothing is perfect. Incidentally, the hand brake operates on a separate set of DRUM shoes inside the rear rotor - it does not apply the discs at all.

If oyu dont feel a vibration when braking, i would not worry about it. If you do, you have found your problem.

Thanks all for the answers.

No vibrations when I brake, but I sometimes feel small vibrations in the steering wheels, that's why I took the wheels off in the first place. But coudln't see anything wrong, I think it's simply the wheels than need a balance.

And yes, using a torque wrench

If you have vibrations in the wheel at speed when you're not applying the brakes, you need to have your wheels balanced. You may want to find a shop that does road force balancing since our cars wear unevenly - especially on the rears.
