If you’re looking to upgrade your braking system, the Baer 12" SS4 Rear Brake Kit is a solid choice for your classic GM Full Size Passenger Car from 1971 to 1976. This kit features the S4 4-piston caliper, which is mounted to a robust 12-inch, one-piece slotted and drilled rotor that’s zinc plated for added durability. Trust me, this setup not only looks good but performs even better.
The S4 caliper is designed with D.O.T compliant dust and weather seals, so you can tackle those rainy days without worrying about grime getting into your system. It uses the popular DR1 or HB100 pad type, which means replacement pads are easy to find. Plus, Baer’s unique backing plate serves a dual purpose: it’s not just a caliper mount, but it also houses a modern one-piece park brake shoe assembly. That’s right, you’re getting a complete package here.
Another thing I really appreciate is the stainless braided hoses included in this kit. They’re a nice touch that improves both the look and the performance of your braking system. And if you’re running 16-inch wheels or larger, you’re in luck because this kit fits most of them without a hitch.
Now, let’s talk specs. This kit is specifically designed for GM Full Size Passenger Cars with OE Large Pattern 10/12 Bolt Bearing on Axle (BOA) Housing Ends. The caliper, manufactured right in Phoenix, AZ, is CNC machined from high-quality US-sourced forged or billet aluminum and comes in a sleek black powder-coated finish. The hard anodized aluminum pistons and stainless steel abutments ensure you're getting a reliable and long-lasting system. The rotor itself is vented and has an outside diameter of 12 inches, with a thickness of 1.020 inches, which is perfect for performance applications.
To sum it up, if you’re restoring or upgrading your classic ride, this Baer 12" SS4 Rear Brake Kit is worth considering. It’s built to perform, looks great, and fits a range of models like the Buick LeSabre, Oldsmobile Delta 88, and Pontiac Catalina. Just make sure your axle is set up correctly, and you’ll be stopping on a dime in no time.
