| In this image of Dirk Ault�s brake master, you can see that the stock proportioning valve has been retained, along with the stock distribution block, hiding behind the vacuum hose. The master is the Ford SVO, aluminum cylinder, using the adapter between the stock booster and master. The adapter is necessary because the bolt pattern of the stock booster uses 4 bolts, while the �USA� masters use 2 bolts. |
| Rod�s white car has a Pantera Performance Center �Ford� master, with the adapter to the stock booster. A Wilwood proportioning valve is plumbed into the rear brake line going to a �Line Lock� device, then down to the rear brakes. The stock distribution block and brake pressure switch is retained. |

| Terry Aultman�s brake system is seen next. This is a Hall product. Notice that the booster vacuum line attaches towards the top of the booster. This is because the booster has been rotated 180 degrees, to align the bolts going thru the firewall foot box. Either some new holes need to be drilled in the foot box plate, or the mounting studs need to be relocated on the booster. |
| In this image you see another Ford master. Compare some of the above images and you�ll notice that the brake lines exit the master on the driver�s side on some models and exit on the passenger side on other cylinders. My preference is to have the lines exit on the side closest to the fender, providing some protection from being damaged by objects (tool box ?) sliding around in the front trunk. |

| Tony Harvey�s system consists of the �Chevy� booster and master, but the vacuum line originates in the stock location, looking from the front it is in the �7 O�clock� position. He ran the lines from the driver�s side around to give the space necessary to add pressure locks (blue). |
 |
| Richard Boschert has the �Chevy-based� system. He retained the stock distribution block, but added not one, but two Wilwood proportioning valves, one for each half of the system. This allows him to fine tune (play with) either end. At the time of this photo, both valves were turned all the way in, providing no bias to either end of the car. Below, is a further collection of images of various brake master systems. |
