Sometimes things evolve in a race car over time. Such was the case of the brake system on this car.
While trying to make the stock C5 calipers work in extreme racing conditions, as I understand it, one of the things that Richard and crew did before I was part of the team, was to use a brake fluid recirculator system to deal with boiling fluid problems. This meant a lot more plumbing than a non-recirculator system. Pretty much as soon as I started with the team they had already moved away from the recirculator system and then very shortly there after we moved to use the big StopTech calipers and associated quality racing pads and fluid. This got rid of the fluid boiling issues. However, all those earlier lines were still on the car, which you can see here.
That aluminum box that is attached to the brake system is a rather ingenious prototype unit by Jim Hausler that measures the brake pressure for both front and rear circuits and then, with the flip of a switch, turns an Auto Meter tach into a brake bias meter. Very cool item, and we have used it continuously over the last 15 years or so, but with the introduction of the ABS system I believe we are no longer going to be able to run this.
