Just wanted to post that I did away with my power brakes and did a DIY hydrobooster set up. I used a booster from a 2005 denalli, and made my own lines. Wow what a improvement in brakes over power brakes. I am loving the brakes, stops on a dime. Excellent upgrade. The biggest cost of the DIY method was making the line. I would say my total cost was around $200-250. Night and day difference.
