This braking system is designed with an S4 4-piston caliper paired with a robust 12-inch, one-piece slotted and drilled zinc-plated rotor. The S4 caliper comes equipped with D.O.T compliant dust and weather seals, ensuring durability in various conditions, and it accommodates the widely used DR1 or HB100 pad types. What’s really neat about Baer's design is the unique backing plate, which not only serves as a caliper mount but also cleverly integrates a modern one-piece park brake shoe assembly. Plus, you'll find stainless braided hoses included for added reliability. The 12-inch SS4 is compatible with most wheels that are 16 inches or larger, making it a versatile choice for your ride. This system is specifically designed to fit 1982-92 GM F-Body cars featuring the OE Saginaw 10 Bolt C-clip (BIH) drum brake housing ends.
