As I approached the intersection I could see another car coming to the stop sign at a high rate of speed, and sure enough he ran the sign.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I was driving my 2000 C2 about a week ago in a parking lot when a parked car backing out of its spot came close to backing into me as I passed. It was a newer 7 Series BMW no less, but to the drivers credit there was a jacked-up pick-up truck parked next to him obstructing his view. When I realized that the driver of the BMW did't see me and was not going to stop I quickly applied the brakes and the car stopped instantly( you have to love PCar brakes) but my front tires locked up it the process making a loud squeal. Driving home late tonight I approached a 3 way intersection in which the other road had a stop sign. As I approached the intersection I could see another car coming to the stop sign at a high rate of speed, and sure enough he ran the sign. Luckily, I was only traveling at about 30MPH as it was a back road and I was able to stop well short of the other car but during the panic stop my front tires locked again. Why are my front tires locking even though my car has ABS? I have never experienced this with any of my other cars equipped with ABS. When I turn on my ignition key the ABS light comes on but it then turns off when the car is started which means the system should be functioning properly. Also, my car has Michelin Pilot Sports which are fairly new, maybe 25% worn. Any feed back would be appreciated.

POST 2Original post

you sure they locked completely?? Mine lock and the tires make short squeles, but I feel the pedal shocking and keep complete control over the steering.....

POST 3 / ORIGINAL POSTEROriginal post

Nicolaas - I didn't feel the pedal pulsating and the squeal was very loud. I am not sure about keeping steering control because both times I stopped very quickly without needing to steer. Maybe they didn't lock completely but it sure sounded like they did and again I have never experienced this with other ABS equipped cars. Thanks for the feed back.

POST 4Original post

it feels a lttle diffrent in these cars due to the weight over the back tires and the front being so light. are all your tires the same make an model and n rating? are they the proper sizes tire pressure set properly?

POST 5Original post

Find an empty stetch of road and do a panic stop from 60 MPH or more. See if the fronts lock. Chances are they won't. If they do see your dealer.

POST 6 / ORIGINAL POSTEROriginal post

All of my tires are the proper size and all are the same make and type. Also, they are all inflated to the proper pressure. Porsche recommends 36 PSI all around for my car but I keep mine at 38 PSI because I prefer the feel at this pressure, however I would seriously doubt that this small difference in PSI could be causing the front tires to lock up.
