A thump at the end of braking

Ball joint, brake caliper, upper strut mount. It really needs to be inspected at a tire and alignment shop. If they can't find it, a tool that will help is called the "Chassis Ear". It's a set of six microphones, a switch box, and head phones. You clip the microphones to suspect parts, then listen and switch between them while driving. Be aware many mechanics have never seen or even heard of this tool, but most new car dealers have them. You might be able to borrow one from an auto parts store that rents or borrows tools.
