If you're looking to upgrade your braking system on your classic Chevy, this Baer 13" SS4+ Rear Brake Kit is a solid choice. It’s built for the 1958-64 Chevy Full Size Passenger Cars that have the OE Large Pattern 10/12 Bolt Bearing on Axle (BOA) Housing Ends. You’ll get that extra bite you need without sacrificing style.

Let’s break down what makes this kit stand out. First off, you're getting a 4-piston S4 caliper, which is no joke. It’s made right here in Phoenix, AZ, from CNC machined US sourced forged aluminum. The powder-coated finish not only looks good but also adds a layer of protection against the elements. Plus, with hard anodized aluminum pistons and stainless steel abutments, you won’t have to worry about corrosion messing with your performance.

What’s more, the rotors are a 2-piece design, slotted and drilled, with a zinc-plated surface. They come pre-assembled with high-grade stainless hardware, so installation is a breeze. The 13-inch diameter means you’ll be clearing those 17-inch wheels and up without any fuss. Just a heads up, these will fit snugly with a 5x4.75 lug pattern.

One of the cool features of this kit is the unique backing plate. It not only mounts the caliper but also houses a modern 1-piece park brake shoe assembly. Talk about clever engineering! And yes, it comes with stainless braided hoses, which means you’re getting durability along with performance.

For those who like to tinker, the rotor thickness is .810 inches, and the surface type is slotted, drilled, and zinc-plated. That means you’re getting optimal heat dissipation and performance when you really need to stop on a dime. Plus, the dual seals on the caliper keep dust and moisture at bay, so it’s built to last.

So, if you own a Bel Air, Biscayne, Brookwood, or Impala from '58 to '64, this kit is designed specifically for you. It’s all about enhancing your ride’s stopping power while keeping that classic aesthetic intact. Trust me, your ride will thank you.
