I hear a rumbling noise when i press the breaks. Could this be my rotors? on 2003 Toyota Sequoia

Recently changed the front brake pads and since then I hear a rumbling noise when I press my foot on the brakes. It does get louder as I come to a complete stop.

Asked by for the 2003 Toyota Sequoia
No the rotors have not been resurfaced.
First start by getting the rotors resurfaced
My 2001 grand caravan makes same noise mainly when I am in drive and pressing on brakes. Also it squeels and makes loud noises like,that. Cant figure it out need help
