If you're looking to upgrade your ride's braking performance without sacrificing that classic 15-inch wheel look, the Baer SS4+ rear brake system is worth a serious look. This isn't just any brake kit; it's a thoughtfully designed piece of engineering that packs a punch in a compact package. With its S4 4-piston caliper paired with an 11-inch, 2-piece slotted and drilled rotor, you'll notice the difference the moment you hit the brakes.

One of the standout features here is the stainless steel brake hoses included in the kit. They’re tough and built to last, plus the calipers come equipped with D.O.T. compliant dust and weather seals. So, whether you're cruising through rain or mud, you can trust these calipers to keep debris out and maintain performance. And let’s not forget about the NAS high-grade stainless hardware that holds everything together; it’s pre-assembled and ready to go right out of the box.

Now, for those of you running a stock Ford 9-inch big bearing housing, this kit is a perfect fit. It’s designed to accommodate both 5 x 4.500 inch and 5 x 4.750 inch wheel bolt patterns, giving you flexibility in wheel choice. Just keep in mind that this system doesn’t include a park brake assembly or cables, so if that’s a must-have for you, you’ll need to source those separately.

So, why should you consider the SS4+? Well, it brings all the benefits of Baer's larger brake systems but in a size that fits comfortably within 15-inch wheels. It’s ideal for those who want to maintain that classic look while still having the option to upgrade to larger wheels later on. And everything you need is included in the kit—hoses, fittings, and all—except for the park brake components.

Let’s talk about the S4 caliper itself. It’s built for performance with four 10mm cross bolts that ensure maximum stiffness. Plus, it features stainless steel abutments and noise suppression springs, so you won’t have to worry about annoying squeaks. The pistons are hard anodized aluminum, and the internal crossover design ensures efficient fluid flow. With dual seals to meet D.O.T. specifications, you can count on reliable performance in various conditions.

The calipers also come in a striking red powder coat finish, but if you’re looking for something a bit different, custom colors are available. And yes, they’re 100% made in the USA with materials sourced right here at home. If you’re into that clean, matched look, you can also get these calipers for the front, ensuring your ride looks as good as it stops.

In short, if you’re serious about your brakes and want something that’s engineered for performance while keeping that vintage vibe, the Baer SS4+ is a solid choice. Get ready to feel the difference.
