When I brake my left front wheel makes a hammering sound if I apply a lot of pressure to the pedal. Plus the brake wear light has been flashing as I drive and while braking.

I just replaced the front pads and rotors with ate premium rotors and pages pads.

Also replaced the front lower ball joints a few months ago.

I'm at a loss at what it could be and i do not really want to just throw money at it.
