It is much smarter to split the brakes front to rear. This is what is
done on almost all race cars so that you can balance the ratio of braking
front to rear. Most cars such as NASCAR have a knob that the driver can
adjust while driving to vary the braking ratio. This is generally done by
having a balance bar between the two master cylinders with a pivot point
that moves so that one master cylinder see more force than the other.
Look at the Wilwood Catalog for an example of this.
