Front right tire locks up

What is your question?

When driving and braking after about 15 minutes the car slows down and only the right tire locks up the car won't move in drive and the brakes are hard to push down. But once we bleed the brakes on that side it unlocks and it's good to go. Already replaced master cylinder, brake booster, brake fluid reservoir, pads and rotors, caliper on right side and brake line. Have no idea what to try next
