Baer Sport Baer Brakes 12 Inch Rear SS4 Brake System with Park Brake for 67-73 Mustang - 4262243S

If you’re looking to upgrade your classic Mustang's braking system, let me tell you about the Baer SS4 rear brake system. This setup features a solid 12-inch one-piece rotor that’s not just any rotor—it’s directionally vaned, which helps with cooling and performance. The 4-piston S4 caliper is mounted on a billet backing plate that’s not only sturdy but also houses a modern park brake assembly. This isn’t your typical drum-in-hat setup; it uses the same shoes as the late model Corvette C5/C6, making it a more efficient and reliable option. Trust me, once you feel the difference, you’ll appreciate the upgrade.

The SS4 comes complete with everything you need—stainless steel brake hoses, fittings, park brake cables, and all the hardware. You won’t have to hunt down extra parts or worry about fitment issues. Just make sure you’re working with a 1967-1973 Ford Mustang that has either a 9-inch small bearing rear or an 8-inch rear with standard bearings. This system clears most 15-inch wheels, but it’s always a good idea to verify with a template just to be safe.

Why go for the SS4?

  • It pairs perfectly with the Track4 front brake system, so you can have a cohesive braking setup.
  • The backing plate is fully machined, giving it a clean look and solid performance.
  • With the Banksia park brake, you’re getting a modern solution that works better than traditional setups.
  • All the components are designed for easy installation and maintenance.

Let’s talk about the S4 caliper:

  • It features 4 robust 10mm cross bolts to ensure maximum stiffness.
  • Stainless steel abutments and noise suppression springs mean quieter operation.
  • The pistons are hard anodized aluminum—lightweight but tough.
  • It’s got an internal crossover design and dual seals that meet D.O.T. specs for dust, weather, and pressure.
  • Plus, the caliper has a hand-painted machined logo that adds a nice touch.
  • When it’s time for replacements, you’ll be happy to know it uses a common 4-piston pad (P/N DR1).
  • Choose from standard colors like red, black, or silver, with custom options available if you want something unique.
  • And yes, it’s 100% made in the USA with US-sourced materials.

In short, if you want a reliable, high-performance brake system for your Mustang that looks good and works even better, the Baer SS4 is a solid choice. You’ll get the stopping power you need without compromising on style.
