Car pulling to side when brakes applied

When braking my car pulls to one side. I’ve replaced both brake roters (doesn’t pull as bad now). What is next, caliper and/or hose on side that is pulled too?

After replacing the caliper and hose - what would be step #3 to replace?

In your driveway, jack up BOTH front wheels at the same time. By hand, spin one front tire then the other. They should both have an equal, small, amount of drag. If one is noticeably tighter, replace BOTH calipers. While the front end is off the ground, check the steering and suspension for worn parts…

Maybe the brake on one side isn’t working. The rubber hose may be collapsed. Compare the flow from the bleeders.

BTW, I am confused by the working. Have you already replaced the hose.
