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