My dad and I are installing a power brake upgrade on his mostly original stepside 3100 series truck. We are converting from the original frame mounted master cylinder with lines going to 4 drum brake setup. Question. He wants to leave the drum brakes installed for now, but wanted to make the braking easier for him to drive the truck as he gets older. Can someone recommend a brake line kit that we would use to run from new firewall setup. We don't care if they are steel or stainless, truck is garaged all the time. We would prefer a preformed set since neither of us are experts at running brakes lines.
