I have rebuilt many of the C-4 masters, and thousands of the C-2,C3 masters.
In looking at the vacuum boosters on the ZR-1's, I notice how ugly that computer wiring harness is, and how ugly the computer looks sitting where it is.
With a HYDROBOOST brake booster, which runs off of the p/s pump, the wiring harness can be run under the booster. The battery can be relocated to the rear compartment, and the computer put in it's place.
The stopping power of a Hydroboost is unbelievable! It can deliver up to 2000psi to the calipers at idle pump speed.
We can use a more conventional master cyl, say of of the C-5, which is 1 inch. This gives you a much firmer pedal, and the stopping power will stop the car faster than you can accelerate.
Many pluses start to stack up with this system.
