If you're looking to upgrade your ride's stopping power, the Baer SS4 rear brake system is worth a serious look. This setup features a solid 12-inch one-piece rotor that's been slot and drilled, giving you that extra bite when you need it most. The real star here is the S4 4-piston caliper, which is mounted to a unique billet backing plate. This isn't just a pretty face; it also houses the Banksia one-piece park brake assembly. Trust me, this design is a game changer compared to the old drum-in-hat systems. It’s modern, efficient, and works like a charm.
Now, let’s get into the nitty-gritty. This kit is designed to fit Buick, Olds, and Pontiac 10 and 12 bolt non C-clip rear ends, as well as hybrid 3.150-inch bearing-on-axle ends with non-flush mount bearings. Just a heads up: it doesn’t come with park brake cables, so make sure to grab those separately if you need them.
What makes the SS4 special? For starters, the 12-inch directionally vaned rotor is a perfect match if you’re already running the Track4 front brake system. The fully machined billet backing plate not only looks great but also securely holds the Banksia park brake assembly, which uses the same shoes as the late model Corvette C5/C6. You’ll get everything you need right out of the box—hoses, fittings, and hardware included.
When it comes to the S4 caliper, it’s built tough. It features four 10mm cross bolts for maximum stiffness, stainless steel abutments, and noise suppression springs to keep things quiet. The pistons are hard anodized aluminum, and the internal crossover design ensures smooth operation. Plus, you’ve got dual seals that meet D.O.T. specs for dust, weather, and pressure. And let’s not forget the stylish machined logo with a hand-painted finish.
These calipers are easy to maintain, using a common 4-piston pad (part number DR1) for hassle-free replacements. They come standard in a sleek silver powder coat finish, but you can also choose red or black—custom colors are available too. Whether you’re looking for front or rear systems, you can achieve that perfect cosmetic match across your setup.
Oh, and did I mention that these are 100% made in the USA with US-sourced materials? You can feel good about your purchase knowing you’re supporting local manufacturing. If you're serious about performance and reliability, the Baer SS4 rear brake system is a solid investment for your ride.
