any easyish upgrades for brakes ?

[sweetk30]

looking to ditch the factory single line master on firewall and vac/booster thingy under cab .

would like to just go all on firewall with true 2 line master for safety .

82 c60 366/4speed / drum-drum brakes.

read a bit and asked a few hydroboost swap places they say its not good to do hydroboost with drum/drum combo .

so looks like I need to keep it vac booster system .

thanks for any links or help .

main reason for change over is #1 safety #2 old stuff is all shot or about dead .
