Originally the Suburban was set up with a four-wheel disc brake master cylinder without power assist, but it has since been upgraded to GM Hydro-Boost that uses power steering fluid pressure instead of vacuum for power assist brakes. The brake lines were routed using Goodridge braided stainless steel lines from Orme Brothers that go to two adjustable Wilwood proportioning valves mounted under the dash so the brakes can be dialed in on-the-fly for precise control.
