Thanks for the post. I have looked at a lot of the kits out there, some are better than others. However since none of those offering kits actually makes the HB unit, rather they are sourcing it from some place else and the fact that there are a variety of HB units available I feel that I can assemble a system for less money than a kit.
To this end, I have no intentions of putting "used" brake parts onto any of my cars, I am not sourcing parts from a junk yard, I will be buying parts from someplace like Rock Auto.
Braking seems to be a bit of a subjective issue; what one guy thinks is good another finds poor. I have a variety of vehicles to include a 70 Challenger RT with a 440 and factory PB (Disc/Drum), 73 Cuda with a 416 that 4 wheel manual disc, an 01 Viper, a 10 Challenger RT, etc. So I have a decent idea of how I want my cars to stop.
In this case, I want to explore a Hydro-boost system mainly because I can and since everyone raves about them I want to see what it is all about. That said, I am very confident I can built a HB system for quite a lot less than $700. Its not about saving money, its about doing something myself instead of paying someone else's markup.
