This braking system is designed with a 4-piston S4 caliper that’s mounted to an 11-inch, two-piece slotted and drilled rotor, which is also zinc plated for added durability. The S4 caliper comes equipped with D.O.T compliant dust and weather seals, and it works seamlessly with the popular DR1 or HB100 pad types. You'll find that the billet aluminum hubs are pre-assembled with premium bearings, all packed with Redline synthetic grease, and topped off with billet dust caps for extra protection.

The rotors are thoughtfully pre-assembled using high-grade NAS stainless hardware, ensuring everything is built to last. Plus, all the necessary mounting brackets, stainless braided hoses, and hardware are included to make installation a breeze. The 11" SS4+ is crafted just like Baer's larger braking systems but is designed to fit perfectly within 15-inch wheels, making it a great fit for classic cars like the 1971-73 Ford Mustang, 70-74 Maverick, 1971-73 Mercury Cougar, and the 70-74 Comet with OE Disc Brake Spindle.
