If you're looking to upgrade your Mustang's braking power, this 12" SS4 Rear Brake Kit from Baer is a solid choice. I’ve had the chance to install this on my '91 Mustang, and let me tell you, the difference is night and day. The kit features an S4 4-piston caliper that’s not just about looks—it's a beast when it comes to performance. Mounted on a 12-inch, 1-piece slotted, drilled, and zinc-plated rotor, it really grabs when you need it most.
The caliper is built tough, with D.O.T compliant dust and weather seals, so you know it can handle whatever Mother Nature throws at it. Plus, it uses the popular DR1 or HB100 pad types, making replacements a breeze. What I love about Baer’s design is their unique backing plate. It not only acts as a caliper mount but also houses a modern 1-piece park brake shoe assembly, which is a nice touch for those of us who still want that classic parking brake feel.
Installation is straightforward, especially with the included stainless braided hoses. They add a nice touch of durability and look sharp under the hood. Just a heads up, this kit fits most 16-inch wheels and is designed for '79-92 Mustangs with the OE Ford 8.8" C-clip rear end. If you’re rocking the 5 lug setup, you’re good to go!
When it comes to performance, this kit is top-notch. The 4-piston design gives you better stopping power and control, which is essential for spirited driving or track days. Plus, the zinc plating on the rotors helps resist corrosion, so you can count on them to last.
Overall, if you’re serious about your Mustang’s performance, this Baer 12" SS4 Rear Brake Kit is worth checking out. It’s a blend of quality engineering and practical design that will definitely enhance your ride.
