If you’re looking to amp up the stopping power on your classic GM A-Body, the Baer 13" SS4+ Rear Brake Kit is a solid choice. This kit features a beefy 4-piston S4 caliper paired with a 13-inch, two-piece, slotted and drilled rotor, all zinc-plated for durability. You can count on it to handle the heat and keep things cool during those spirited drives.
Now, let’s talk about the caliper. It’s made right in Phoenix, AZ, and has a powder-coated finish that not only looks sharp in Hugger Orange but also stands up to the elements. Inside, you’ve got hard anodized aluminum pistons and stainless steel abutments, which means less noise and a smoother ride. Plus, the dual seals keep dust and moisture out, ensuring reliable performance no matter the weather.
The rotors come pre-assembled with high-grade stainless hardware, so you won’t have to worry about rust or corrosion. And with a rotor thickness of .810 inches, you can expect solid braking without fading. The unique backing plate isn’t just a pretty face; it doubles as a caliper mount and houses a modern park brake shoe assembly, which is a nice touch for those who want to keep things tidy.
Now, about fitment: this kit is designed for the 1964-77 GM A-Body cars, fitting those with the OE small pattern 10/12 bolt bearing on axle housing ends. It also works with the hybrid 10/12 bolt non-flush mount 3.150" bearing. And don’t sweat the wheel size—this setup fits most 17-inch wheels and larger, so you can keep that aggressive stance without any hassle.
Overall, if you’re serious about your ride and want a brake system that matches your passion, this Baer kit has got your back. It’s built to last and designed to perform, making it a worthwhile upgrade for any classic car enthusiast.
