I am running larger 4 piston Outlaw (read Willwood) calipers on the front of my v6 track car, with 911 M calipers on the rear. I installed a brake bias adjuster knob initially but my rears lockup under heavy braking no matter the adjustment. Switched to a Tilton bias adjustment with the notched rod with multiple positions and still no change. I cannot tell that there is much difference in the pressure to the rears. They will lockup no matter the position under heavy braking. They are not sticking. Not sure which direction to go from here. I am running Hawk blues front and rear. Perhaps a less aggressive rear pad? And yes the factory proportioning valve was removed.
thanks for any help guys. LC |

Before doing anything I would corner balance with you in the car. My formula car experience has been that corner weights have a huge effect on things like this. Messed up corner weights can do really wacky things...
