I had a similar problem on my 4X4. I dont have Hydraboost--I have a huge double diaphragm booster. The brake pedal would get sucked down and apply the brakes. I called the manufacturer and it turned out I did not hook up the pedal return spring. Something simple but overlooked. When the spring was hooked up the brakes worked fine. Hopefully, yours is an easy fix too. BTW-- do you really need brakes on the dyno.

Is this the first time you have tried the car with the Hydraboost? Mine did the same thing but for only a few times. Did you follow the start up/break in procedure? Just get a couple miles on it and you will be in love!! Good luck tomorrow with the dyno.

we had a similar problem. check your pedal and booster rod. one may be too far out.

Also did you change your pedal rod to pedal lever angle at all?
