This system showcases the impressive S4 4-piston caliper, paired with a robust 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. 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 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 Ford 8.8" C-Clip Rear Ends with a 2.5" axle standoff and 5 lug configuration.
