I had the hydro boost brake system installed by my trustee mechanic on a 1989 F350 Dually two wheel drive. I have struggled to get the stock brakes to perform like I wanted even after replacing everything. I’ve drove about a hundred miles with the hydro boost system and it’s exactly what I was hoping it would be. The brake system performs like a 20 year newer vehicle. My mechanic was very impressed and said he was definitely going to install the system in one of his projects.
Thank You
