I just replace the front rotors and pads and I started hearing a noise like when the pads are worn down but when I'm driving around 40+ and while braking what do you guys think it is?

Can quick check visually to make sure pads are in correctly...a pad may be placed in backwards causing the backside to make contact with rotor. Also make sure there are no brackets or schims touching rotor.

 

I'm pretty sure there in correctly but ima check that web I get on break and could it be that is the rear rotors lol I just check them and one of them is not flat is like lumpy lol well since I got the car I never change the rear rotors and that's 3 years ago

Any luck in finding out the noise culprit since your last post?
