I'm bringing this back months later to say thank you to everyone who helped me piece this together and get it installed. My 17-year-old son daily drives our Bronco about 40 miles every day in LA traffic. A few nights ago the brakes saved his life. Some bonehead decided to make a left turn from the far right lane as my son was closing at 40 mph. He jumped on the brakes and they stopped with authority just inches from hitting the other car. This is stopping power that a few months ago the truck never had. He called me clearly shaken and grateful that we spent the money and effort to do the hydroboost install. Without everyone here, this would have ended very differently. Thank you all for the advice.
