My wheel tilts to the left (to the disc side) any solution
It is a normal effect with disc brakes, the major reason why most motorbikes have left and right  discs at the front. Braking on the left side only will cause a slight deformation of the left leg of the fork, pushing it backwards. The wheel follows.

I'd guess you have quick releases on your bike. If you do, try to tighten it a bit more. Through axles have been introduced to help better secure the wheel in the drop outs but also to stabilize the fork.
