This system showcases the impressive S4 4-piston caliper, perfectly paired with a sturdy 12-inch, one-piece slotted and drilled zinc-plated rotor. You’ll appreciate the D.O.T compliant dust and weather seals on the S4 caliper, along with its compatibility with popular DR1 or HB100 pad types. What’s really neat is Baer's innovative backing plate, which not only serves as a caliper mount but also cleverly incorporates a modern one-piece park brake shoe assembly. To top it off, stainless braided hoses are included for added durability. The 12-inch SS4 is designed to fit most wheels that are 16 inches or larger, making it a versatile choice for your ride. It’s compatible with rear ends featuring Ford 9” early big bearing housing ends (5x5.00"BC).
