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 utilizes the popular DR1 or HB100 pad type for reliable performance. One of the standout features is Baer's innovative backing plate, which not only serves as a sturdy caliper mount but also incorporates a modern one-piece park brake shoe assembly. Plus, you'll find stainless braided hoses included for added durability. The 12-inch SS4 is compatible with most 16-inch or larger wheels, making it a fantastic fit for 1982-92 GM F-Body Cars equipped with the OE Saginaw 10 Bolt C-clip (BIH) drum brake housing ends.
