This system boasts a robust 4-piston S4 caliper paired with a 13-inch, two-piece slotted and drilled zinc-plated rotor. The S4 caliper comes equipped with D.O.T compliant dust and weather seals, and it utilizes the widely favored DR1-C pad type. You'll find that the rotors are pre-assembled using high-grade NAS stainless hardware, ensuring durability and reliability.

What sets Baer's design apart is its innovative backing plate, which not only serves as a caliper mount but also integrates a modern one-piece park brake shoe assembly. Plus, we've included stainless braided hoses and hardware for added peace of mind.

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