Thanks for Edjumacating me! And I Hope it helps others too. Like I said, I'm an old skool mechanic from the late 70s early 80s. And I was taught by an Older Skool mechanic. So all he taught was "The Rotors are Warped!" No explanation as to why. So now I'm a bit more Knowledgeable!

 

i though brake pulsing is warped rotors, and i too also get a noise randomly, its a humming noise, and also the brake pedal vibrates....i think its a abs issue because my abs light is also on
