This braking system is designed with the S4 4-piston caliper, perfectly paired with a 12-inch, one-piece slot, drill, and zinc-plated rotor. You’ll appreciate the D.O.T compliant dust and weather seals that come with the S4 caliper, along with the popular DR1 or HB100 pad types that make maintenance a breeze. What sets Baer's system apart is its innovative backing plate, which not only serves as a caliper mount but also cleverly incorporates a modern one-piece park brake shoe assembly. Plus, stainless braided hoses are included for added durability. The 12-inch SS4 is compatible with most 16-inch or larger wheels, making it a great fit for your ride. This system is designed specifically for the 1994-2004 Ford Mustang (SN95) with the OE Ford 8.8-inch solid axle.
