Baer Brakes 12" SS4 Rear Brake Kit

If you're looking to amp up your ride's stopping power, the Baer Brakes 12" SS4 Rear Brake Kit is worth a serious look. This isn’t just another brake kit; this is a piece of performance engineering that’s been crafted with care right in Phoenix, AZ. You get a 4-piston S4 caliper that packs a punch, paired with a 12-inch rotor that’s slotted, drilled, and zinc plated. Trust me, this setup is built to handle some serious heat.

Now, let’s get into the nitty-gritty. The S4 caliper features dual seals that keep out dust and moisture, which is a big deal if you want your brakes to last. Plus, it uses the popular DR1 or HB100 pad type, so you won’t have to hunt down specialty parts when it’s time for a change. And those hard anodized aluminum pistons? They’re not just for show; they help with heat dissipation and performance.

What’s really cool about this kit is the unique backing plate. It acts as a caliper mount and houses a modern 1-piece park brake shoe assembly, so you’re not just getting a brake upgrade; you’re also keeping your parking brake functional and reliable. And with stainless braided hoses included, you know you’re getting durability where it counts.

Worried about fitment? This kit is designed for rear ends with Ford 9" early big bearing housing ends and fits a 5x5.00 bolt pattern. It’s compatible with most 16" wheels and up, so you can easily swap it onto your ride without a hitch. Just a heads-up, though: it clears 35s on a 2024 Tundra with only minor trimming, so if you’re running big tires, you’re in good shape.
