Crazy brakes
 

This started with rear driver caliper sticking on my 2006 f250. I replaced both rear brakes. Then different caliper stuck I would bleed to let loose. I have since replaced booster pump Master cylinder all four calipers brakes and lines. And most recently abs module. On my way home tonight and passenger front started to drag. The pedal gets tight and I’m stuck again until I bleed. I hope somebody can help me with this I am no mechanic obviously because I have parts changed the whole brake system thanks for any help

For starters, are you sure the brake pedal is coming all the way up?
