A word of caution: A dual master cyl. conversion such as this may not work as intended! If pressure is lost front or rear, the pedal will go nearly to the floor before the remaining brakes engage. If total pedal travel is anything less than the OEM application, you will lose all braking and probably crash!
Save your neck and your car by testing your setup. When everything is hooked up and bled, you likely will have good brakes with little pedal travel. But now, open a front bleeder screw and try a panic stop. If the rear wheels don't slide and the pedal goes all the way to the floor, the system failed. Time to re-engineer! Repeat on the rear brakes and the fronts must lock up or again, fail.
