ABS Kicking in when it shouldn't be?

[ocelot]

I had 18" Cobra-R's on my 96' GT since I got it, and i've got a set of stock wheels that I went to put on so I could do some burnouts and have some fun before I sold them. So I put 3 of the wheels on when on the last one, one of the studs twists right in half. I replaced the stud (it was on the left rear) and put the last wheel on then went driving around. Under really hard braking the car is fine and won't use the ABS unless it really needs it like it should. However when i'm rolling at like 10mph coming to a red light or something and I hit the brakes, when its almost completely slowed down the ABS will come on and off like crazy. One thing I should say though, is that the front wheels have horribly uneven treadwear and theres hardly any tread left. Could that be causing that? I thought they would have enough traction to make those kinds of stops but i've never driven with tires this worn down to experience what the ABS will act like. I guess i'll put the other wheels back on later but I just want to know what might be causing this?

Thanks,
Brian

It is probably a bad ABS sensor. Also, it is unsafe to drive on bald tires...

Are they easy to replace? How much in parts would it be?


And unsafe to drive on bald tires? I thought thats when they were at the peak of performance! lol All i'm doing is driving around parking lots and doing burnouts before putting the other wheels back on so no concern there.

If there's a difference in the overall diameter between the front and rear that will confuse the heck out of the abs and cause the fronts to kick in early. My car always does it if you don't pull the fuse before doing a burnout at the track(and using the brake to hold it in place).

mine does that too with the stock wheels and new tires. I first noticed it when I put the speedcal in when doing new gears.
