Car makes popping sound when making hard turn or hard dip and extreme grinding sound when braking?

OK, this is all the front passenger side tire. My brake light has been on forever, but I haven't heard a squeal from the brakes that precedes changing usually. When I turn quick left or pull out of my driveway (large decline then flat) turning left it makes a loud pop once. When I'm driving really slow and put the brakes on or sometimes just when I've let go of the brakes and am driving but been at a light for a while I get an extremely loud grinding sound but only from that one side where the popping comes from. How do I figure out whats wrong, and fix it? Serious answers only please, Im checking back once a day.
