Squeaky noise after changing brake pads

Did you resurface or replace the rotors?

no i didn't resurface or replace the rotors

Check to see if there is a glaze built up on the rotors. That can cause a noise. I have to ask another question. Does the noise change with speed? Does it change when turning? Have you checked to make sure the backing plate behind the rotor isn't bent and touching the rotor as it turns?

i am not sure if it changes with speed, but what i notice is that i hear the noise at slower speed for instance if i am in busy traffic/ go-slow traffic and moving at 15-20mph.

At faster speeds i don't hear the noise at all.

I will check the backing plate and revert but the noise is coming more from the front driver side

Let me know what you find, Also, make sure that the rotor isn't glazed.

checked and the back plating is not bent, but here's what i noticed.

start up the car and after driving for a 2 mile distance, the noise starts, a grinding one coming from the front wheel. park it after that distance wait a while say like an hour or 2, start it initially no noise while driving, but after the 2 mile distance the grinding noise starts again from the brakes and front wheel

i really don't know what to do, now i 'm opting for getting new rotors and brake pads from Wagner to confirm if the issue is from both the rotor and brake pads. I 'm also suspecting the caliper but not sure, the rotors currently have a shining reflection when i look at it, the ones in front wheel, see attached an image

It's hard to tell from the pic, but they could be glazed. However, if the pads are good, you shouldn't hear a grinding noise. Does the noise change with speed? Does it change when turning?

yes the noise changes with speed, at faster speeds you don't hear it, at lower speeds its more pronounced, also while driving at lower speeds, i noticed that when depress the brakes while moving the sound reduces.

I was thinking it could deal with a wheel bearing. However, since it changes when you depress the brake pedal, it truly sounds like a brake issue.

i also noticed that after driving that long, the rotors heat up

Are one of the calipers sticking?
