Wheel or brake noise
 
Hi guys.

I have this squeak noise. When I start it doesn't have noise. After drive while and wheel and brake become HOT, then after I stop, slowly move, I can hear this squeak noise.

Brake pad and rotors are new. I removed and reinstalled it but I still have this noise.
I think it is from front passenger side but I can't find what this is.

What do you think?
Thank you for you guys opinions.

Volume up and when I slowly move, you can hear the noise.

Is that squeaking when lightly touching the brakes or without touching the brakes?

Most likely causes....

Without touching- Dirty glide pin keeping brake on lightly or loose/bent heat shield.

With touching- Grease on pads or rotor.

Without brake.
just release the brake pedal and slowly move I have this sound. But only after hard drive so brake is HOT condition.

Probably a glide pin issue. Did you grease the glide pins?

If you did it'll collect dust and dirt and may cause it to drag a little.

Thank you. I will replace the glide pin to new one and I will update you guys.

Honestly I'd just use a green scrubby pad.

I replaced the pins but I still have the noise. I haven't had a chance to hard drive but I was able to hear it after freeway ride.

And your dust shield is tight and not bent? Do you know if it is both sides or just one? Put the windows down and drive down a narrow alley/road that has concrete walls on both sides, forwards and backwards. If it does it in both directions it's probably not a pad issue. Did you see any glazing on the pads? Did you bed them in when you changed them?

It doesn't have noise when I reverse.
Only right after hard drive and hard brake,... then slowly move. when I push brake pedal lightly, noise is gone.
when I release my foot from brake pedal, noise come back.
And funny thing is next light, if I try to record with my cell phone, there is no noise.
hmm


And today, noise was louder when I try to make a right turn.(of course I pushed brake before turn) and noise is coming from passenger side for sure.
only one side.

It is hard to capture with my cell phone.
Right for example today, I drove about 15 minutes and was hot day. when I slow down at traffic, and slowly move, I heard the noise. When I try to capture it with my cell phone, there is no noise at all next 2 light stop. and after 4th light stop, there was noise, and I pull out my cell phone and try to capture but there is no noise at all.
But one thing sure is that I usually hear the noise right after when I push drive hard(go fast and strong stop, and go)and when I drive mild for while, there is no noise.
