Our Master Power Brake (No. BM1521KA) booster kit arrived with virtually everything needed for installation: booster, master cylinder, distribution block with warning switch, vacuum hose, and installation hardware. Not shown here is the power-brake pedal assembly, also included. The GM distribution/proportioning-valve block combo shown here is optional. You may have to do your own line fabrication or purchase lines, with fittings and flares, already made. Any seasoned auto parts store or hydraulic-line shop can make lines for you.
