I have a 98 integra and I have a problem when I brake a noise comes on like a grinding noise or like a finger nails running on the chalk board noise like a worn out brake running metal to rotor noise. I checked the brakes when I got home and all four brakes are fine (They are about a year old brakes with still good thick pads on it.) So I tried test drive it again and the sound still comes on. I even tried the emergency brakes and it too a grinding niose comes on. My ABS light does not come on either. Last two months I did a oil change on the car and the niose went away but now it came back on again and it is driving me crazy cause I can't find the problem that is causing it. Can you help me suggest what can be the problem?

Does the car sit for awhile? If so, it is probably rust build-up on the rotors.

If not, and you said the noise is present when you put the emergency park up, then it is your rear brakes. Did you check the inboard pad as well? Try taking the caliper off and checking out both pads on each corner.

I tried everything already.I look at the back brake pads so they are also fine too. Also looked at the back side of the calipers too it also looked ok as well. It is like when I drive and braking at a stop light or stop sign it comes on. After the noise comes on I tried pressing the brakes a couple of time to get rid of the noise. But it continues to do that every time I come to a stop or a stop sign. Still have no idea.

So you pulled both rear calipers off and the inboard pad on both sides were fine?

You may just have some noisy semi-metallic pads. Try getting some rough sand paper and roughing up the friction material on the pad and the rotor face as well. You may also want to get a file and file the edges on the pads as well.

Ok Thank I give that a try. After looking at the brakes I noticed that the bearings on the both front right and left axis are broken can that make the the noise as well?

Yes! Bearings can grind at you.

I thought you said the noise was coming from the rear? In either case, replace those bearings asap.

The grinding sound like it is coming from the rear but it is not too. It sounds like it from the front passenger side. Like I was saying when pressing on the brakes it will start the noise, and even when using the emergency brakes to stop it sounds too. I already checked the brakes both the back pad and front pad of the front and check the back too, but all pads seems to be fine. I am going to try sanding down the rotors and brake pads like given to see if it works. Other than that I am fixing the axis or bearings to see if that is a problem but just don't have the doe right now and replacing the axis is costly.

Well sanding down the friction surfaces isn't a bad idea, but if they are really glazed over and hard then it won't really do much, you will have to replace them.

However, if those wheel bearings are loose, replace them! That is most likely you're issue
