Warped disc?

Set off with disc lock on... first time I've done it, FFS.

Now when I'm riding, I can see the caliper moving left right left right, faster as I speed up.

There is no visible damage after this, can I expect anything else to be wrong?

Does it stink of fish fingers, lie to you constantly and sometimes fuck off for a week and reappear as though nothing as ever happened?

Definitely warped.

Put it on the centre stand and put some weight on the rear.

Spin the front wheel and see if there is excessive binding on a part of the disc.
If it is obviously warped, then you may even be able to see it when you spin the wheel.

Try braking from speed to check for pulsating in the lever.
