 28 Turning our attention...  28 Turning our attention to the firewall, several modifications are needed. First, drill this hole in the firewall directly below the large hole where the pushrod passes through. There is a dimple in the firewall indicating hole placement. The dimple was supplied for cars with original power brakes, but with manual brakes, the hole wasn't necessary.  29 Open up the large hole...  29 Open up the large hole at the top to allow the power booster to fit. Mustang Country used an air-powered tool with a small hacksaw-blade attachment. A hand hacksaw might also work since the appearance doesn't matter; the opening will be hidden by the brake booster. The directions and a supplied gasket or template illustrate how much material to remove. The directions also say to enlarge the two smaller holes on either side of the large hole to allow the brake booster to fit. By test fitting the booster/master, we discovered that we didn't have to do this on our car, but this will vary from car to car.  30 Now the new brake pedal...  30 Now the new brake pedal and modified pedal support can be installed along with the steering column and steering wheel. Note the large holes in the pedal support where the clinch nuts used to reside. Those two holes are visible to the right of the brake pedal.  31 Before installing the...  31 Before installing the brake booster and master, install the supplied junction block to the car's existing brake lines according to the Master Power instructions. The two front brake lines are joined at the rear of the block and the single rear line at the front. The master cylinder is then joined to the junction block with the two lines installed on the right side of the block as shown.  32 Next, the master cylinder/brake...  32 Next, the master cylinder/brake booster is installed and secured to the firewall using the supplied nuts. These are installed from inside the car underneath the instrument panel where the pedal support is located.  33 The brake booster requires...  33 The brake booster requires a vacuum source from the engine. Master Power supplies a vacuum hose that can be cut to fit, and it's simple to run the hose from the booster to a fitting on the intake manifold. If no fitting is in place, Master Power supplies one for installation on the manifold.  34 Complete the installation...  34 Complete the installation by connecting the vacuum hose to the brake booster.  35 Here's the completed brake-booster/master-cylinder...  35 Here's the completed brake-booster/master-cylinder installation. The setup looks great, works perfect, and has a cool OE-look to it. Bleed the car's entire brake system, and enjoy the huge upgrade of going from manual drum to power front disc brakes.
