    Brake noises

    I have searched and found numerous posts from members with the same problem as me but no genuine solutions. (I posted this in the regular 500 forum as I have seen complaints from numerous members Abarth and non-Abarth alike)

    I have a pre-owned Abarth with 19,000kms (11,800miles) and from the moment I drove it off the lot the brakes have been making noise.

    The first and most frequent is a high pitched squeal when applying light brake pressure which goes away when you press harder or let off the brakes. After a couple of these it'll go away for awhile but return frequently.

    The next and most disturbing is a grinding on metal noise when the car is rolling forward from a stop. It sounds like something is rubbing onto the dust shield around the rotors. This occurs less frequently.

    I have taken the car back to the studio with a concern that the initial safety and inspection wasn't done correctly since I have these brakes noises as well as other issues but they said they can't find anything wrong with the car.

    The front rotors also have an obvious pad mark on them. Like an outline of the pad, maybe from sitting in the same spot for too long. I noticed it when I picked up the car but figured it'd go away after awhile but over 1,000kms later it's still there.

    I have a very good mechanical knowledge and have worked on many brakes for many different cars and motorcycles in the past. I have also worked at a Chrysler service department and know they don't make very good brakes but this seems to be a common issues as others have complained about it.

    I have a similar problem. Bought my 2013 Abarth brand new over a year ago, and the metal grinding sound from the right front started at around 1500 miles. The car now has 14,000 miles and it still occurs intermittently. I have tried to pinpoint when it happens, such as I notice it more when the car sits after being in the rain, or sitting over night during the warmer months so there is dew, and it only happens going slow (i.e. 10 mph or less, and more prominent turning either direction). The car is at the dealership now, and they cannot find anything wrong. Say they have checked the brakes and everything. Any feedback would be appreciated!!

    I get the light squeal in cold/damp weather for the first few stops if the car has sat a while. The grinding noise could be a backing shield which got knocked into a rotor on a parking curb. For the OP, I think the rotors should be turned to get that spot out, then see if the noises go away.

    I took the car in yesterday to get my winters installed and the mechanic did hear a squealing. He said it was due to alot of snow packed into the wheels but I told them that not the case since the brakes have been making noise since waaay before the snow fall. They cannot find anything wrong and recommend a $150+ brake service. I told them no thanks.

    I hear my squealing during light braking after having driven awhile. It has been nothing but damp and cold here lately but some days I don't hear it.

    It does sound like the dust shield for the rotor is grinding on something but it doesn't always do it, and if the shield has been knocked out of alignment to make contact with the rotor, why wouldn't it do it all the time.....or even most of the time?

    Thanks. Come spring I'll clean and lubricate the brake calipers myself. While I'm in there I'll go over the rotors lightly with some sand paper or a pad on a drill and see if those marks come off.

    Rocket, seems like we have the same problem. Are you familiar with automotive components/mechanics? Does it sound like it might be coming from the A/C compressor? I heard it last night just as I clicked on my Defog (and I know that usually clicks on the A/C compressor)....it might have just been a coincidence cause the other times I was sure it was coming from the front right brake.

    What you seem to be describing is the light coating of corrosion (rust) that forms on brake rotors from sitting for an extended time (several hours) in a high humidity environment. This usually goes away after a few applications of the brakes which 'scrubs' the corrosion from the rotors and restores the relatively smooth surface.

    I have owned numerous vehicles with different front brake setups and I know what you are reffering to. If Rocket is describing the same issue I am then this is not the issue. If Rocket only get this only at the beginning of a drive then it might be the problem but I frequently hear the noise after a while of driving. Mild or spirited driving.

    I'm not sure if I'm experiencing the same thing you are, as I've dealt with brake squeal almost daily in the these winter months, but even before then in the fall I heard a much different sound at times, a sort of metallic "rubbing" sound, that would only be audible rhythmically, every time the wheel reached a certain rotation point. At first I was concerned it might have been a bearing. I'm not sure whether it was related to the brakes or not, but it's only been audible from my rear right wheel (specifically) at very low parking lot speeds. Much as described above, it seemed to be prevalent when in the process of changing direction.

    The only problem with bringing it into the dealership is that the sound isn't easy to reproduce. At first I thought it was brake dust, but this is a much different, and rather distinctive sound. I've had the brakes inspected by my personal mechanic. Nothing out of the ordinary from a quick review.

    I think this non squealing, metallic rubbing/scraping sound is a common issue. We can't all be having similar sounds coming from the same part of the car during the same driving conditions as a coincidence.

    When the weather is better here I'll pull the front right wheel and take a gander.
