brakes feel bumby when brakes are applied

Sounds like a rotor issue. bring it for a quick check

sounds like a brake pulsation or could be a lower control arm bushing that hasnt gone bad.

Xineho, If you're feeling a pulsation when applying the brakes, it's likely due to warped rotors. The rotors could even be damaging your new brake pads. Sooner rather than later, bring it into a shop and have them check your brakes. The longer the issue persists, the more you can damage those brake pads.
