    I have a 04 pt cruizer and when I apply the brakes it sounds as if it
    is metal to metal (grinding). I took it to my local dealer to have it
    checked out. They said that is normal (that they rust over night). But
    they still do it in the middle of the day . What shoulld i do ???

    they rust overnight?

    i've driven vehicles that have spent 20 years int he wettest places
    imaginable (scotland) fording all the time, and they've never 'rusted

    Think they're taking the piss. Never heard 'they rust overnight'
    before. Mtals oxidise all the timRust is iron oxidising. They don't
    only do it during the day, or on the 3rd full moon in april, or any
    other specific time. Now, if your discs are rusting, you got serious
    problems, and it certainly is NOt normal.

    Metal on Metal is generally the rivits ont he pads hitting the
    discs/drums. heck, just take a look at the pads yourself. its not
    hardtake the wheel off and on many vehicles, its just one or two bolts
    to get the caliper off, and thus the pads.Of course, given what you've
    written, i would take it to someone you trust since you're probably
    going to struggle with what to do, getting them on and off.

    What model (does it have rear disks or drums, turbo or not)? Does the
    grinding go away after a couple of stops? Is it grinding in the front only?

    Well you're about to hear it again. The discs on my Intrepid will rust
    overnight during certain times of the year. They've all been like that
    I have had 5 Intrepids). Back down the driveway in the morning with
    light pressure on the brakes, and it sounds like the pads are scraping
    on sandpaper. It's gone within the first 2 or 3 stops.

    Due to the material that the linnings are made out of you will get some
    grinding noise especially on cool wet or dewy mornings. The rotors WILL
    DEVELOPE RUST and untill you hit the brake pedal a few times to remove the
    rust this noise will be heard.

    Do you live in Bikini Bottom?
    Thought about looking into some alternatives, like MMC?

    Same on my '95 Concord and the '86 LeBarron GTS before it.

    However if it doesn't go away I'd look at the condition of the pads and
    A few months ago I had a front wheel scrapping noise when braking that
    wasn't the pads or rotor. The front wheel bearings were worn out. The
    BIG bill for bearings fixed it. About 80K miles, much better than the
    20K miles my wife got on her 2001 front wheel bearings.

    Its a kind of brake technology used in, amongst other things, early
    lotus elises. They sue an aluminimum disc, discs actually get thicker
    as the pads wear, the pads building up an interface coating on the
    disc which is what provides the friction.

    no iron, so no rust.
