Hopefully when you reassemble it all will be fine. Very often when you hit a tope, sleeping policeman or road hump depending what country you are living in, at speed it can disturb or even distort one of the steering components. Sometimes something as simple as loosening off all the components; axels, bolts on brake calipers and on motorcycles fork clamps and ride slowly and grab the brakes enough that the suspension compresses and the brake components realign with the disks. Do this several times and then retighten everything again and try riding it again.
The visual scoring on the disk could be from light sand or dirt embedded in the brake pads, if you run your thumb nail across the scoring and can feel it there is damage and it will wear your pads faster on that side. To check if the disk is warped remove it and place on a piece of glass with a smear of oil on it. If there is a high spot you will see it quite easily. Remove the oil with rubbing alcohol afterwards.
I was a motorcycle mechanic in Dublin for 30 plus years at a time when motorcycles were often the only form of motor transport in some families. Lane sharing and dodging potholes was a way of life and bouncing off curbs and hitting cows all too familiar... So loosening off the steering components and grabbing a handful of brake with a dose of speed is often enough to pull everything back in line.
