If you're looking to upgrade your braking game, the Baer 13" SS4+ Rear Brake Kit is where it’s at. This isn’t just any brake kit; it’s packed with features that make a real difference on the road. The heart of this system is the 4-piston S4 caliper, which is mounted to a solid 13-inch, 2-piece slotted and drilled rotor. And yeah, it's zinc-plated, so it’s built to last against the elements.

Now, let’s talk about the caliper. Made right in Phoenix, AZ, the S4 caliper sports dual dust and weather seals that keep grit and grime out, ensuring durability. It uses the popular DR1-C pad type, which means you’re getting reliable stopping power without the fuss. Plus, the rotors come pre-assembled with high-grade stainless hardware, so you know they’re ready to take some heat.

One of my favorite features? Baer’s unique backing plate. Not only does it serve as a caliper mount, but it also houses a modern 1-piece park brake shoe assembly. That’s right; you’re getting a solid setup without the hassle of piecing everything together. And for those who care about the details, the kit includes stainless braided hoses that add both style and reliability.

Now, about fitment: this kit is designed for rear ends with a GM small pattern 10/12 bolt C-clip housing. So if you’re running a setup with a 5x4.75” or 5x5” bolt pattern, you’re in luck. It fits most 17” wheels and up, clearing those larger tires with ease. Just a heads up, it’ll clear 35s on a 2024 Tundra with a bit of minor trimming if you’re looking to beef up that stance.
