If you're looking to upgrade your ride's stopping power, the Baer 12" SS4 Rear Brake Kit is a solid choice for those classic GM full-size passenger cars from '65 to '70. This kit features the S4 caliper, which is a 4-piston powerhouse that really makes a difference when you're hitting the brakes hard. The caliper is mounted to a robust 12-inch rotor that's not just any rotor—it's a one-piece, slotted, drilled, and zinc-plated beauty that helps with heat dissipation and keeps things looking sharp.

One of the standout features of the S4 caliper is its D.O.T compliant dust and weather seals. These seals are a game changer, especially if you plan on taking your ride out in less-than-perfect conditions. Plus, it’s designed to work with the popular DR1 or HB100 pad types, so you’ve got options when it comes to replacement pads. And let's not forget about the backing plate—it’s not just there to hold everything together. It also houses a modern one-piece park brake shoe assembly, making your life a little easier when it comes to installation and maintenance.

The kit comes with stainless braided hoses, which is a nice touch for durability and performance. You won't have to worry about those hoses bursting under pressure. And if you’ve got 16-inch wheels or larger, you’re good to go with this setup. It's designed to fit most of those larger rims, so you can keep your ride looking slick while also improving your braking capabilities.

Now, for the specs nerds out there, here’s what you need to know: this kit is specifically made for rear axles in GM Full Size Passenger Cars with OE Large Pattern 10/12 Bolt C-Clip (BIH) housing ends. The caliper comes in a striking Hugger Orange, which not only looks great but also features a powder-coated finish for extra protection. The pistons are hard anodized aluminum, and the stainless steel abutments and noise suppression clips help to keep everything running smoothly and quietly.

With a rotor thickness of 1.020 inches and a vented construction, these brakes are built for performance. So whether you're cruising down the highway or hitting the back roads, you can trust that this brake kit will give you the confidence you need to stop on a dime.

To sum it up, if you own a '65 to '70 Chevy Bel Air, Biscayne, Brookwood, Caprice, Impala, or Malibu, this Baer Brake Systems 12" SS4 Rear Brake Kit is definitely worth considering. It's a performance upgrade that not only enhances your stopping power but also adds a bit of flair to your classic ride.
