brake problem help please!!!!

i have a problem with my car beeping everytime i apply the brakes and i just replaced the pads and machined the rotors if anyone knows why it is doing this please let me know i have no clue what it is.

Assuming you mean a squeal (not the horn beeping), it is probably that the pads have not seated yet, and/or they made from a material that squeeks when they are cold, or all the time. Since they are new, as long as they work OK, give them some time.

its not that it started before i put the new pads and its not squealing its beeping like if you left your lights on and turned the car off.

Does the car have abs? I've known of some luminas that have had similar problems with sensore making noise when the brake pedal was depressed. I'm not sure what the fix was but I do know that it was in the abs. Of course if you don't have abs then this will be useless.
