Is it normal to see the master cylinder and power booster move a bit when braking? just got new master cylinder and calipers installed. Brakes improved but not by much, pedal will still go to the floor before stopping

Good afternoon,

Did you bleed the system? It sounds like you have air in the system. I would pressure bleed the system as there may be air trapped in the lines.

Yes, it is not abnormal for the firewall to flex a little when applying the brakes.
