Power steering/axel question?

So, a few weeks ago, my passenger axle ball joint and lower control arm snapped. Anyways I fixed that, but the driver's side is loose and the rubber covering over the axle is ripped! Is that deadly dangerous? And today While fixing a whining issue. The reservoir kept showing full, but the steering wheel felt empty! Would that be the steering power pump possible? Either way I did a full steering wheel spin and filled the reservoir and accidentally added a bit of brake fluid because both the bottles are blue. I drove to the store and it’s seeming quieter. I was just wondering if I was in danger of crashing the vehicle before I can flush it. It’s like 90% PS & 10% BF.
