When brakes are applied it squeaks

When my brakes are applied my brakes squeak only when i slightly apply the brakes but when fully applied it does not squeak. Does this mean I need new pads?

Take your tires off and check...

How far down does the pedal go?

I agree with 4x4forLife. The best thing to do is jack it up and pull the tires to see how much brake pad you have left. Also check the roatars t osee if they are warped or have any scars. If everything looks good it could be build up on the brake pads causing the sqeak. Might try using brake cleaner on the pads and then wipe them clean.

Under normal conditions the leading edge of the brake pad gets to a sharp edge and chamfering the edge will stop the squeek. Higher end pads come with a large chamfer to stop this for a very long time.

Ok I brought the SS to the dealer and they said the brake pads are like brand new and they could not duplicate the sound. This only happens at low speeds say 25mph and below. Should I just take a look myself? Is there anything I can do if everything is normal?

Anyone willing to help would be appreciated.

If the weather is nice I will be taking the brake pads off once again and taking pictures. I did notice that the rotor is loose a bit once I take the wheel off. It has been a while since I have done work on my own vehicle. Should this happen with the loose rotor being like that?

Maybe its just dirt, get some good brake cleaner and spray everything down. Or I know autozone sells this little packet of brake quiet, but I have never used it or know if it really works. The loose rotor with the wheel off is normal, when you put your wheel on it will sandwich the rotor between the wheel and hub.
