This system showcases the impressive S4 4-piston caliper, perfectly paired with a 12-inch, one-piece slotted and drilled zinc-plated rotor. The S4 caliper is designed with D.O.T compliant dust and weather seals, and it accommodates the widely-used DR1 or HB100 pad types. One of Baer's standout features is its innovative backing plate, which not only serves as a caliper mount but also cleverly houses a modern one-piece park brake shoe assembly. Plus, you'll appreciate the inclusion of stainless braided hoses for added durability. The 12-inch SS4 is compatible with most 16-inch or larger wheels, making it a versatile choice for your ride. This setup fits 1982-92 GM F-Body Cars equipped with OE Saginaw 10 Bolt C-clip (BIH) disc brake housing ends.
