Like Mike says, I'm always here at least twice a day. Lat-G members can always look at my profile and get in touch with me directly as a result. First, take a deep breath, relax, and know that you now have my attention - I will work with you to get your scenario straightened out right here.
99% of this type of concern stems from having the adjustable brake pedal rod set incorrectly to not allow the brake unit to acheive a full state of release when the brake is not applied. Go ahead and crack loose the brake pedal rod adjustment under the dash and back off the adjustment (lowering the brake pedal height adjustment considerably to make sure the brake unit isn't being engaged or preloaded when not in use)
OR disconnect the brake pedal rod from the brake pedal entirely for diagnostic purposes. If the PS system comes to life and all is now well, then we all chuckle about how adjustable items are infinitely more troublesome than non adjustable items.
I have a few questions: What model number brake assist system? What type of vehicle? 1st gen Camaro? Or? What type of PS pump? What type of steering gear? The more you can tell me about your specifics, the more accurate I can be within the diagnostic discussion. In cases like this, I also like to advise that a complete bypass of the hydraulic brake assist unit be performed, as the problem may not be related to the hydroboost unit at all. You can either take the two high pressure lines loose of the brake unit and then play some fitting games to interconnect them, or the high pressure hose from the PS pump to the brake assist unit can sometimes reach the steering gear as an easier bypass solution. As stated in the very first part of the system installation instructions, the power steering system must be in 100% condition to operate the hydraulic brake assist properly, so let's make sure the PS is functioning.
Let us know what you find and we'll take it from there.
