This system showcases the impressive S4 4-piston caliper, perfectly paired with a robust 12" one-piece slot, drilled, and zinc-plated rotor. The S4 caliper is designed with D.O.T compliant dust and weather seals, ensuring durability and reliability. It utilizes the widely compatible DR1 or HB100 pad type for optimal performance.

One of the standout features of Baer's design is its innovative backing plate. Not only does it serve as a caliper mount, but it also cleverly houses a modern one-piece park brake shoe assembly. To top it off, stainless braided hoses are included for added strength and flexibility.

The 12" SS4 is a versatile choice that fits most 16" or larger wheels, making it a great fit for 1970-74 GM F-Body Cars with OE Small Pattern 10/12 Bolt C-clip (BIH) housing ends.
