(T) Pads touching discs

Are they supposed to?

I think the answer is no, but jacked the car up the other day and noticed the pads are touching the discs on both front sides, I can still move the wheels easily enough but when i spin one of the wheels and let go they stop almost straight away.

Could this be the reason to me warping 2 sets of discs and a whirring noise while driving?

its normal, you only need a nats whiskers gap,
warping can be from hard braking then sitting at the lights/junction with foot on the brake, the bit of disk trapped under foot pressure on the brakes, don't cool down as quick as the rest of the disk

If you had a big gap between pads and disks, you would get stones and stuff jammed in them, which would do a nice job of scoring the disk. Normal for a tiny bit of interference.

Also would have loads of pedal movement before the brakes started working.
