This brake system is designed with a 4-piston S4 caliper that’s paired with a robust 13-inch, two-piece slotted and drilled rotor, all beautifully zinc-plated for durability. The S4 caliper comes equipped with D.O.T compliant dust and weather seals, ensuring it stands up to the elements, and it utilizes the widely-used DR1-C pad type for reliable performance. Each rotor is pre-assembled using high-grade NAS stainless hardware for added peace of mind.

What sets this system apart 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. You’ll also find stainless braided hoses and hardware included, ensuring everything you need is right at your fingertips.

The 13-inch SS4+ is compatible with most 17-inch or larger wheels, making it a versatile choice for many setups. It fits rear ends with Dana 60 or Mopar 8-3/4" car housing ends, adding to its adaptability.
