Pulls to the right Pulls to the left
I just purchased (a few months ago) a 2001 996 Carrera cabriolet with 64K. I have what I think is a problem with the car pulling sharply when breaking to one side or the other. If I stop at high speed or slowing down at a light with the steering wheel straight on the car it brakes perfectly straight. (I do this with my hands off the steering wheel to test although I can feel it with hands on). If I turn the wheel slightly to the left or right and break (as if I am preparing to turn) the steering wheel and car pulls sharply to the side that the steering wheel is slightly turned toward. I have never had this problem on all my other cars where the wheel tends to pull the car straight or very little pull even with the slight wheel turned. My other cars did not have as flat of a profile or as wide a tire as the 996. Will a positive toe cause the braking to pull like this? I have tried this on different roads and it is not dependent on road profile.
The car has:
New tires and good brakes pads and rotors. I have cleaned and rebuilt the front calipers (did not seem to have any corrosion) and bled system but this did not affect the problem. The suspension seems tight and all wheels do not have any drag on them when spun by hand. I can’t feel any play in the steering rack.
I don’t want to just play the parts replacement game without some idea if this is a real problem or a characteristic of wide flat profile tires unlike what I am use to.
Some have suggested:
Wheel alignment although the old tires did not show uneven ware.
Just replace front calipers, rotors and pads and soft brake lines.
Replace powers steering pump or rack.
ABS or PSM system faulty (ABS seems to work properly when engaged) and have same problem with PSM turned off.
Am I just not use to the wide flat tires? Again if the steering wheel is straight no pull at all with your hands off the wheel with a slight bias to the wheel car pulls sharply and dramatically to the side bias to wheel direction.
Am I just chasing a normal condition of wide flat profile tires?
