GM A, F, X Body Front Power Disc Brake Conversion Kit - A123-1


Simple complete premium GM drum to disc brake conversion. Get original looking disc brakes with Easy Bolt on parts so you can do this conversion in your garage

  • Complete with 9 in. booster, master cylinder, Standard ride height spindles, USA made Carbon Metallic pads, Original style caliper mounting brackets and splash shields, SSBC USA made adjustable proportioning valve, adapter lines, grease seals, bearings, grease caps, DOT rubber flex hoses, spindle nuts and hardware.
  • 11" Rotors available with optional Turbo slotting and Xtra Life plating or cross drilled
  • Zinc plated calipers with period correct inlet. New slider pins and anti rattle clips
  • Will not fit some factory 14" wheels including most Pontiac factory wheels, we suggest 15" wheels. For those 14" wheels look at kits A123-22 and A123-23
  • SSBC uses our USA made adjustable Proportioning valve rather than the GM style combination valve. GM style valve results in no adjustment for rear brakes causing much lower rear brake performance. SSBC valve requires no additional plugs or fittings and is much easier to plumb and bleed
