Introducing our impressive brake system, featuring a robust 4-piston S4 caliper paired with a 13-inch, two-piece slot-drilled, zinc-plated rotor. This S4 caliper is designed with D.O.T compliant dust and weather seals, ensuring durability in all conditions, and it utilizes the widely favored DR1-C pad type for reliable performance.

We’ve pre-assembled the rotors using high-grade NAS stainless hardware, ensuring everything fits perfectly right out of the box. One of the standout features is Baer's innovative backing plate, which not only serves as a caliper mount but also cleverly incorporates a modern one-piece park brake shoe assembly. To top it off, we include stainless braided hoses and all necessary hardware for a complete setup.

The 13" SS4+ is designed to fit most wheels that are 17 inches or larger, making it a versatile choice for many setups. It’s compatible with rear ends that have GM Small Pattern 10/12 Bolt Bearing on Axle (BOA) Non-Flush Mount Housing Ends (5x4.75", 5x5"BC).
