i drive a 2007 acura tl type s

like 1 week ago.
i changed right side rotors and for the left side resurfaced it
and new brake pads at the pep boys.
and first i thought its was ok.
but after 4 days, i started hearing high pitch screening sound when i press the brakes.
the sound is not the metal scratching sound.
it's like really high pitch sound that makes you never heard that sound again.

it seems like high pitch screening sound starts when the brake pads get heat up.

any suggestion? maybe its the wheel alignment?

 

It sounds like the coating on the brake pads wearing off. If it lasts for more that a few days have pep boys look at it.

 

I am guessing you did not bed the brakes in. If not, what you're hearing is the build up of the brake transfer film, which is normal when installing new pads to fresh rotor surfaces.

This pattern will continue until there's a relatively even deposit of film.

 

thanks to both of you.
will try that advise and see if it work or not.

 

but the funny thing is that when i used to drive 01 accord coup, i didn't need to bed the brakes and stuff.

 

Some setups are simply inherently sensitive by default...i.e. what you're dealing with now.

 

When you hear the noise, press the brake pedal harder, noise stops?

 

when the noise starts, the sound doesn't go away until the car stops.

why?

 

you drive TL-S and you chane brakes at pep boys? The problem is your new brake pads, change to premium brand pads and your problem will be gone. Pep boys are super duper cheap place with cheapest parts.

 

Replacing only one rotor and resurfacing the other is not what you want to be doing either! Bed the pads and see what happens
