At times you may have a slight gap or "play in your brakes pads seated inside your calipers. This may be causing the "thump" that you hear when applying. Try going on a test drive with a technician so that you can explain when it happens what you are hearing.

A thump may indicate something is loose but you really need a mechanic to diagnose the problem

Hello Pat- Without seeing the vehicle, my best guess is a worn or damaged suspension part. Usually a bad bushing can cause this- hope this helps.
Thanks, Super Girls Auto.
