This braking system is designed with a robust 4-piston S4 caliper, perfectly paired with a 13-inch, two-piece slotted and drilled rotor that’s zinc-plated for durability. The S4 caliper is equipped with D.O.T compliant dust and weather seals, ensuring reliable performance in various conditions, and it utilizes the popular DR1-C pad type for optimal stopping power.

What’s more, the rotors come pre-assembled with high-grade NAS stainless hardware, ensuring everything stays securely in place. 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, stainless braided hoses and hardware are included for added reliability. The 13" SS4+ is a great fit for most wheels that are 17 inches or larger, making it a versatile choice for those looking to upgrade their ride. This system is compatible with 1970-74 GM F-Body cars featuring OE small pattern 10/12 bolt C-clip housing ends.
