grinding on front breaks while moving stops when pressure applied

What is your question?

Changed rotor and pads smelt metal burning and smoking. I replaced caliper pins and still have grinding sound but not a constant grinding. Grind,grind,grind and then the squealing starts loud until I push my breaks. What do I check next,i don't know what the problem could be and show me my breaks and all parts that needed when I changed my pads,like squeal pins,etc. what should and where parts should be.
