Upgrade the rear braking performance of your classic GM A-Body with the Baer Brakes 13-inch SS4+ Rear SDZ Brake Kit, part bae4302309R. Designed for 1964-1977 Chevrolet Chevelle and compatible El Camino applications equipped with OE small-pattern 10- or 12-bolt C-clip housing ends, this complete system combines modern caliper technology, a performance-oriented rotor design, and an integrated parking brake assembly. The kit is intended for most 17-inch or larger wheels, although wheel clearance should always be confirmed with the applicable Baer fitment template before installation.
The system features a four-piston S4 caliper manufactured in Phoenix, Arizona and CNC machined from U.S.-sourced forged or billet aluminum. Hard-anodized aluminum pistons, stainless steel abutments, noise-suppression clips, and D.O.T.-compliant dust, weather, and pressure seals support dependable operation and reduced brake noise. The included DR1-C brake pad type provides a proven friction solution for street and performance applications, while the powder-coated red finish adds a clean, distinctive appearance.
A two-piece slotted and drilled zinc-plated rotor uses a billet aluminum hat and is pre-assembled with high-grade NAS stainless steel hardware. Baer Brakes’ dedicated backing plate serves as both the caliper mount and the housing for a modern one-piece parking brake shoe assembly. Stainless braided brake hoses and required hardware are included for a more complete installation. This kit is engineered for select Chevrolet Chevelle and El Camino applications, including the 1964, 1967, and 1972 Chevelle and 1968-1976 El Camino model years listed for this application. Professional installation and final wheel, axle, and brake-system verification are recommended.
