This premium drum to disc brake conversion kit is designed for 1955-1958 Chevy Full Size Impala, Biscayne, and Bel Air models with non-power drum brakes and stock ride height. The kit includes GM style single-piston cast iron calipers, zinc-plated for corrosion resistance, and 11-inch rotors (available with optional dimple drilled, slotted, and plated finishes). It bolts directly to stock drum brake spindles and comes complete with a dual bowl master cylinder, semi-metallic pads, caliper mounting brackets, grease seals, wheel bearings, grease caps, DOT rubber flex hoses, spindle nuts, hardware, and a USA-made proportioning valve. The kit offers a simple bolt-on installation to convert from drum to disc brakes, providing an original look with modern stopping power.
