This system showcases the impressive S4 4-piston caliper, perfectly paired with a 12-inch, one-piece slotted and drilled rotor that has a sleek zinc plating. The S4 caliper is designed with D.O.T compliant dust and weather seals, ensuring durability in various conditions, and it accommodates the widely used DR1 or HB100 pad type. What’s really special about Baer's design is the unique backing plate that 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 16-inch or larger wheels, making it a versatile choice for your ride. It fits 1960-87 Chevy/GMC C10 2WD Trucks equipped with OE Large Pattern 10/12 Bolt C-clip (BIH) Housing Ends and 5 Lug (5x5" BC).
