KIT 84

“In this phase, you will install the brake master cylinder and the brake booster onto the firewall. Then you will install the firewall behind the engine of your Eleanor Mustang.





Firewall and Brake Master Cylinder

Step 84.1

Fit the two keyed posts on the ends of the Brake Fluid Line into these matching holes of the Firewall, orienting it as shown.

I am pretty sure this not a brake line on the real car – it appears to be the nitrous oxide injection rail:

Step 84.2

Secure this Brake Fluid Line into place from the back side of the Firewall with two (2) PS12 screws:

Step 84.3

Fit the keyed post of the Brake Fluid Reservoir Cap into the matching hole of the Brake Fluid Reservoir, as shown:

Secure these parts together from below with one (1) PS12 screw:

Step 84.4

Press the pins of the Brake Master Cylinder into the matching holes on the bottom of the Brake Fluid Reservoir.

The longer pin of the Master Cylinder should be fitted into the thicker end of the Reservoir, as shown. On my model, I super glued these parts together:

Step 84.5

Fit the keyed post of the Master Cylinder into this matching hole of the Firewall, as shown:

Step 84.6

Secure the Master Cylinder into place from the other side with one (1) PS05 screw:

Step 84.7

Fit the tab and post of the Brake Booster into this matching slot and hole of the Firewall, as shown.

This part is inaccurately named a brake booster – it is more likely the nitrous oxide valve:

I love the gauge detail on this part. You can even read the tiny PSI label!

Step 84.8

Secure the Brake Booster into place from the other side with one (1) PS05 screw:

Step 84.9

Retrieve your Chassis assembly from the previous kit. Fit the Firewall down behind the engine, as shown.

While this Firewall is being fitted, there are THREE things I feel we should be aware of. First, I routed the plugs/wires behind the Dashboard off to the left side of the Interior, as shown. We do not want to trap any wires between the Firewall and the Chassis as it is installed:

Second, the Brake Fluid Line needs to wrap around the front of the Air Filter/Carburetors and above the Distributor, as shown:

Third, as the Firewall is lowered into place, make sure the Steering Column fits into this notch of the Firewall (circled below):

Fourth, there are two posts on the passenger-side end of the Firewall that need to be seated into these matching holes of the Right Side Engine Bulkhead:

Step 84.10

Secure the Firewall to the Right Side Engine Bulkhead with two (2) PS08 screws.

In order to install these two screws, I had to gently bend the Front Right Wheel Housing out of the way, as shown:


While I still feel the Brake Fluid Line is actually the nitrous system of our Eleanor Mustang, it definitely looks great in our engine bay!
