annoying brakes!

[Amp438]

I replaced my rotors and pads on my s14 3 months after I bought it and their still pretty new only a few months old, and a few days ago I would reverse and when I hit the brakes it would sound like a party horn was losing air, and now when I drive the rotors sound like its being scratched by something( when driving and worse when braking) what do I do?

Sounds like something is in between the pads and rotor on one of the corners. Put the car back up in the air and start checking each corner to see if something worked loose or if some debris managed to work in between the pad and rotor.

I found the problem. It was the pad was being eatin the wrong way and don't know why it ate it up so quick and bad
