You might have a loose caliper on that side or your pad has become delaminated from its backing, Better get this checked right away

You know I had the same problem and was told it was the power booster. sooo I changed that and still had the same problem. I've been told it is the power steering pump so that is the next to be changed.
If you pop the hood and listen underthe hood or brakes have someone press them and you can find the vibration.

I had the same problem. There is a vacuum hose going to the brake caliper. Check to make sure it is on. I repaced this hose and the thump disappeared.

Check left front ball joints.

Ball joints fixed mine. Front right was my culprit.
