12-inch LS front brake swap kit for 1967-1969 Camaro, 1964-1972 Chevelle and 1968-1974 Nova
When your LS conversion retains the factory drum spindles on a '67 Camaro, '64 Chevelle or '68 Nova the 12" Front Brake Swap Kit for Drum Spindles immediately addresses the need for consistent fade resistant stopping power by providing a clear path to ventilated 12 inch discs and four piston calipers without welding or machining. By mounting brackets onto the factory boss locations the kit preserves precise rotor position and caliper alignment using only basic hand tools and the provided hardware. Cast iron rotors pull cooling air through deep vent channels to resist fade during repeated or aggressive stops while four piston calipers with premium friction pads deliver consistent clamp pressure. A detailed manual guides each torque step and hardware placement to streamline fitment on GM two piece spindles and ensure dependable performance under demanding driving conditions.
Bolt-on Bracket System Simplifies Drum Spindle Conversion
The kit leverages the original factory spindle bosses to secure custom mounting brackets without any welding or machining, making it accessible for DIY installers and professional shops alike. By anchoring brackets directly to the existing boss locations, rotor face alignment is maintained to strict tolerances, preventing runout and ensuring even pad contact. Each mounting point is validated to match GM two-piece spindle specifications, so the caliper and rotor sit in perfect concentric relation from the first bolt. A detailed instruction manual walks through every torque value and hardware placement, guiding users step by step to minimize errors and reduce installation time. All that is required are basic hand tools and the supplied bolts, washers and nuts, delivering a seamless transition from drum to disc braking on classic Camaro, Chevelle and Nova models.
Cast Iron Rotors for Efficient Heat Dissipation
Each 12-inch rotor is cast from a robust iron alloy chosen for its excellent thermal conductivity and strength under extreme braking forces. Deep internal vents channel ambient air through the disc core to draw heat away from the friction surfaces, curbing temperature buildup during repeated stops or spirited driving. Precision turning of the rotor faces and hat mount ensures uniform thickness and tight tolerances, which reduces vibration and contributes to a smooth, predictable pedal feel. The substantial mass of the rotor combined with optimized vent geometry effectively resists warping and maintains consistent stopping power over extended use. As a result, drivers experience minimal fade and more consistent pad life compared to drum setups or solid disc alternatives.
Four Piston Calipers and Premium Pads for Consistent Stopping
The multi-piston caliper design applies even clamp pressure across the full width of the rotor surface, maximizing friction contact and extending pad longevity. Premium pad compounds are formulated to provide a firm initial bite and stable performance under a wide range of temperatures, delivering confident modulation at the pedal. Corrosion resistant stainless steel pistons and hydraulic fittings ensure reliable fluid transfer and full pad retraction after each stop, while the rigid caliper body resists flex that can soften pedal feel under heavy braking. This combination of hardware and material selection produces a direct, linear braking response that enhances driver confidence in both street and performance driving scenarios. Each caliper is factory bed-tested to validate pad retention and seal performance before it enters your hands.
American Made Hardware for Lasting Reliability
All brackets, bolts, nuts and washers in this kit are manufactured in the United States from high-strength steel alloys, then finished to resist corrosion from road salts and moisture. Material thickness and hole placement are engineered to match GM spindle geometry, locking brackets in precise orientation and maintaining pad clearance even under vibration and heavy loads. Fasteners meet or exceed original equipment tensile strength standards, ensuring they remain secure through aggressive stops and daily driving alike. The domestic production of these critical components adds a layer of quality control and traceability, so builders can trust the integrity of every piece. Combined with the robust calipers and rotors, this hardware package delivers a durable, worry-free upgrade that stands up to demanding conditions mile after mile.
