need hydro boost rebuild article
 

I'm looking for a breakdown on the 02 gm hydroboost so I can adjust the pedal effort feeling. I would like to make it like my c3500 pickup (no effort at all!) I called Gm Parts and they said the hydroboost has an internal adjustment but it has been along time since I had one apart. Where can I find some help with this? I also found out that software controls PSI settings to all the wheels. No more proportioning valves. Need to find someone that can program the EBCM (ABS Module)
