Why is there a clicking sound when i drive? Just replaced brake pads

What is your question?

There has been a clicking sound when I drive my car that I assumed was the indicator clip on worn down brake pads. So, I replaced the brake pads and yet, the clicking persists. What could this be?

What makes this problem better or worse?

Sometimes, if I drive for a long time, the intermittent clicking will switch to a persistent grinding/screechy sound
