Recently, my brake pedal started to get softer and softer and now my brakes squeak and squeal under light pressure. Im assuming that it is time for some new pads. There is also a slight shimmy that seems to be comming from the front under hard braking. Do i need to have teh rotors turned or is it time for some new rotors too?? Over all stopping power seems to have decreased quite a bit in the last week or so. Any help and product recomendations appreciated!
