For me its a simple as turning up the volume,....... If you can hear the tires squeel due to excessive breaking when entering a corner,........ your locking them up, (to a degree anyway), which results in loss or less control of the car. GT3 called for higher brake settings than I've found needed in GT4. I start most cars at 5 front and 3 rear. Remember that center of gravity shifts forward under braking, loading the front tires and unloading the rears. Lower rear brake force to prevent lockup and loss of control or fish tailing.

Reason No 2....... Many here at the 'Vault are using the Driving Force Pro wheel/pedal combo which allows a much finer input to the brake pedal than that of the dual Shock 2 controller. Hope I helped a bit, Brian
