I am contemplating upgrading my brakes on the TR250, I have upgraded various other aspects of the car modestly, but have left the brakes stock (all parts new or rebuilt, rubber replaced, so safe and in fine fettle) other than ceramic pads. In looking at brake upgrades and the Toyota 4 pot conversion seems like the most bang for the buck.
I have read the benchmark article and testing on VTR and am impressed with the test results, but also a little confused. The article suggests you upgrade to bigger bore rear wheel cylinders which to my simple way of thinking and understanding of mechanical advantage would mean you would have greater rear braking force, or to put it another way more force/friction applied to the rear brakes for a given pedal effort.
This would seem to me to be counter improving overall braking, if the fronts are more efficient with the four pots wouldn't there be more weight transfer to the fronts on hard braking and more of a tendency for the rears to lock up?
Or do the Toyota four pots change the brake balance equation in other ways so that the bigger rear wheel cylinders simply restore that balance?
