Squeaky noise when brakes are depressed slightly

[jalbert]

Wondered if anyone has experienced this ....on a 1999 intrigue??

Getting high squeaking noise coming from the front wheels, as I depress the brake pedal, and unable to identify the source.
Have taken it to a GM dealer and they have cleaned all four wheels twice.

I'm Squeaked! Help?

I have a 2001 and mine does it too i have taken it to stelership and they said brakes are almost brand new and that sometimes the brakes do this i also talked to a close friend and he said to stop this you have to have the rotors machined and it should stop it i have not done this yet mine only does it if ive been useing the brakes alot or i have been mean to them hard brakeing and hard braking more

Hey was also wondering if you have water or moisture leaking into your headlights? I seem to keep getting a buildup of moisture around it and have tried to seal it with silecone but to no avail. it must be coming in from somewhere else. Any ideas? anyone?

My '99 Intrigue brakes also squeal at low speed, just before final stop or when let off slightly to allow car to creep.
Mechanic said to hose them down; which helped for 2 - 3 days, then the squeal returned.
I've given up.

What you are all hearing is seems to be common friction noise. A certain amount of friction causes your brake pads to resonate or vibrate on the brake rotor. The vibrations are heard in the form of a high pitched sqealing noise. A similar situation in which this happens is when you make a wine glass ring by rubbing your finger on the top of it. If you don't hold enough pressure on the glass with your finger you'll get no sound; push too hard on the glass and you'll also get no sound.

Fortunately, you can get some anti-sqealing lube from a parts store that you put on the back of the pads to dampen or eliminate the noise and it works very well.

High quality brake pads come with noise reducing designs such as shims or angled edges and/or grooves in the friction material to reduce or eliminate noise.

It is also a good idea to roughen up the rotors with 320 grit sandpaper if you are reusing the rotors to avoid "glazing". Glazing is when the brake rotor and the pads become so smooth that they don't work quite as efficiently and also cause a high pitched noise.

If you are replacing the rotors be sure to use brake cleaner to remove all of the assembly/machining lube.

Finally, it is a good idea to break in your brake pads by not stopping abruptly for the first couple weeks if possible; unless of course you need to use them in an emergency situation (DUH!)

Using ceramic brake pads will reduce brake noise too! They're more expensive, but worth it.
