GM Drum-to-Disc Brake Conversion Kits | SSBC-USA

Find the SSBC-USA GM drum-to-disc conversion kit for your Chevrolet, GMC, Buick, Oldsmobile, Pontiac, Cadillac, or other supported GM vehicle. Use the Find Parts That Fit Year/Make/Model search above to narrow the applications, then compare the front or rear kit listings below.

Choose the Conversion That Matches Your Brake System

  • Front conversion: Check whether your vehicle has power or manual brakes, along with the spindle and existing front-brake configuration.
  • Rear conversion: Confirm your axle, bolt pattern, parking-brake setup, and wheel clearance.
  • Complete build: Review front and rear kits by part number. Do not assume that kits listed for the same model share every component.

Kit contents vary by application and can include calipers, rotors, brackets, hoses, hardware, and parking-brake components where specified on the product page. Some kits use billet aluminum calipers manufactured by SSBC-USA in Elma, New York; other components have different sources.

Review the individual product's fitment and kit-specific wheel-clearance diagram with your installer before ordering. If you need help locating a diagram or identifying the appropriate application, call our technical team at (716) 775-6700. The customer and installer make the final wheel-clearance decision.
