Where are the abs sensors

What is your question?

My friend does not take care of her car! Her brakes were shot.... both calipers leaking...and NO break fluid at all when i got it!I replaced them with used ones (not my choice) drivers side works but no fluid to passenger side. I exchanged the caliper but that wasnt it.checked the flex hose ....it trickles....tried blowing it out but there is no fluid coming to that wheel. I was told abs sensor maybe
