This braking system is designed with a robust 4-piston S4 caliper, perfectly paired with a 13-inch, two-piece slot and drill zinc-plated rotor. The S4 caliper comes equipped with D.O.T compliant dust and weather seals and utilizes the well-known DR1-C pad type for reliable performance. You'll find that the rotors are pre-assembled with high-grade NAS stainless hardware, ensuring durability and longevity.

What sets this system apart is Baer's innovative backing plate, which not only serves as a caliper mount but also incorporates a modern one-piece park brake shoe assembly. To top it off, stainless braided hoses and hardware are included, providing you with everything you need for a seamless installation.

The 13" SS4+ is compatible with most 17-inch or larger wheels, making it a versatile choice for your vehicle. It's specifically designed to fit 1971-76 GM Full Size Passenger Cars with OE Large Pattern 10/12 Bolt Bearing on Axle (BOA) Housing Ends.
