This braking system is equipped with a robust 4-piston S4 caliper, paired with a 13-inch, one-piece slotted and drilled rotor that’s zinc plated for added durability. The S4 caliper is designed with D.O.T compliant dust and weather seals, ensuring it stands up to the elements, and it utilizes the widely trusted DR1 pad type for reliable performance.

You'll also appreciate the billet aluminum hubs, which come fully assembled with high-quality bearings that are packed with Redline synthetic grease, along with sturdy billet dust caps. Everything you need is included—mounting brackets, stainless braided hoses, and all necessary hardware.

The 13-inch SS4 is crafted to fit most wheels that are 17 inches or larger, making it a versatile choice for your vehicle. It’s compatible with a range of classic models, including the 1965-69 Ford Mustang, 1962-69 Fairlane, 1963-69 Falcon, 1969 Torino, and 1967-69 Mercury Cougar, as well as the 1966-69 Comet and 1969 Cyclone when using OE drum brake spindles.
