12-Inch Front Disc Brake Swap for LS-Swapped 1967-1969 Camaro, 1964-1972 Chevelle, 1968-1974 Nova
Any LS engine conversion that retains original drum spindles on a first generation Camaro, Chevelle or Nova finds the right solution in the 12" Front Brake Swap Kit for Drum Spindles. This bolt on assembly uses factory spindle bosses to mount four piston calipers and ventilated 12 inch rotors without welding or machining. Cast iron rotors draw cooling air through deep vents while premium friction pads resist fade and ensure a firm pedal feel under repeated stops. Installation requires only basic hand tools and aligns precisely on models from 1967 through 1969 Camaros, 1964 through 1972 Chevelles and 1968 through 1974 Novas.
Precision Mounting Adapts Drum Spindles for Disc Upgrades
This kit leverages the original spindle bosses found on first generation Camaro, Chevelle and Nova to mount disc brake components without altering the front suspension. By embracing a bolt on layout that uses no welding or machining, installers secure caliper brackets directly to factory bosses with standard tools. The result is precise rotor face positioning and caliper alignment that mirror factory tolerances, cutting installation time and eliminating guesswork. Detailed instructions guide each torque specification and ensure consistent rotor runout, so the brake assembly remains stable under repeated use.
Cast Iron Rotors Optimized for Thermal Management
Each 12 inch rotor is cast from a robust iron alloy chosen for its heat absorption and structural integrity. During production, deep vent channels are formed between rotor faces to channel air through the core, drawing heat away from friction surfaces during aggressive braking. Precision machining refines the rotor faces and hat interface to tight tolerances, minimizing wobble and vibration. This combination of mass and airflow management maintains pedal firmness under repeated stops and extends service life by resisting thermal warping.
Four Piston Calipers Deliver Consistent Stopping Power
The four piston calipers use evenly distributed clamp force to maximize pad contact area and improve braking efficiency across the rotor surface. Premium friction pads are formulated to resist fade under high load, offering strong initial bite and a confident feel at the pedal. Stainless steel pistons and corrosion resistant bleed fittings prevent moisture ingress and ensure smooth retraction, while the rigid caliper body resists flex under pressure. Together, these features translate into linear brake response and repeatable performance in everyday driving or spirited runs.
Comprehensive Brackets and Fasteners Ensure Stability
All mounting brackets are formed from high grade steel and treated with a corrosion resistant finish that withstands exposure to road salts and moisture. Quality checks validate material thickness and hole placement for a predictable fit on each drum spindle. The hardware package includes bolts, nuts and washers graded to meet GM strength standards, preventing loosening under hard stops. By maintaining bracket alignment and pad clearance over many miles, this hardware set delivers lasting stability and quiet operation without the need for frequent adjustments.
A precise bolt on solution for LS swaps that balances ease of installation with consistent braking performance.
