Subaru: MY02 WRX ABS Problems

    MY02 WRX ABS Problems

    My MY02 REX has ABS activation problems and low speed when the break is not
    being applied heavily (just covered, just enough for the rear break lights
    to activate) , mostly while turning and mainly on encumbered (rough) road.

    Any body had a similar problem? Keep in mind I just changed the rims around
    and the service Dept has blown out the Callipers.

    Is this a new behavior that started after the dealer touched your brakes? Or
    was the dealer trying to fix them?
    Similar symptoms have been cronic with the new age WRX in the US since the
    beginning.
    Look in the discusion forums over at www.nasioc.com, you will find dozens of
    items over the last 2.5 years. The latest "official" investigation results are
    currently posted in the News & Rumors forum.
    The ABS on mine seems a little oversensitive to me, but it's my first ABS
    equipped car so I have no personal point of comparison. We have plenty of
    "encumbered" roads in my part of the States. Most city streets in Seattle were
    paved 50-100 years ago and haven't been properly rebuilt since.
    After 44,+++ miles it's "normal" for me

    No it wasn't after work had been performed on the car and I forgot to
    mention it only effects the Front Right Hand Side only, its always going off
    at a drop of a hat.

    Anyway I will look into the forums you have pointed out to me and see what I
    can find.


    Thanks Kimball

    You can work around that problem by braking hard before the bump, let the
    brakes go then brake hard again. This is also leads to more ride comfort.

    I am talking about just 1-5 Kmph (mostly pulling into a car park etc..) not
    even applying the break really just covering it.

    If that is true then there is something wrong with your car. Get it
    fixed.

    Most of the US complaints about over-sensitive abs are down the
    heavy-footed driving. Unless the UK spec is dramatically different to
    that in the rest of the world - and I don't believe it is - then you
    have to really stamp on the pedal to make the abs work....even in icy
    conditions. In fact, I'm always amazed at just how brutal you have to
    be. Never made mine work by accident in, I suppose, getting on for 20
    years of driving with abs-equipped cars - mostly Imprezas.

    andrew,

    it's the abs computer being over-aggressive.

    there's some great threads about it on nasioc, as the other poster
    suggested.

    afaik, there's actually a NHTSA investigation going on right now.
    some members have gotten questionairs in the mail.

    do yourself a favor and pull the fuse when driving on gravel or snow.

    Some people have reported a defective or loosely mounted ABS sensor, that sounds
    more like your problem than the general "oversensetive ABS" issue that has been
    debated.

    The US WRX brakes are different (ie cheaper 2 piston calipers) from other
    markets. So software programming and operation might vary noticably.

    Might, but I don't see why. Lots of Imprezas have different brakes
    fitted, including aftermarket. No reason why that should affect the
    abs settings. The so-called 'over-sensitivity' issue is about
    heavy-footed driving. Sounds to me, however, like this guy has a
    fault.

    It really is very simple. If the driver is activating the abs
    unintentionally on a regular basis, then either there is a fault in
    the system or the driver is not modulating his or her brakes properly.
