If you're looking to upgrade your rear braking system, let me tell you about the Baer SS4 setup. This isn’t just another brake kit; it's a serious piece of engineering that I’ve had the pleasure of using. At the heart of this system is the S4 4-piston caliper, which is mounted to a solid 12-inch, one-piece rotor that’s been slotted and drilled for improved cooling and performance. The rotor is also zinc plated, so you know it’s built to resist corrosion and last through the elements.

One of the standout features of this system is the billet backing plate. It’s not just there to hold the caliper in place; it’s designed to house the Banksia one-piece park brake shoe. This modern setup works way better than the old-school drum-in-hat systems that you often see. If you’ve ever struggled with a drum brake, you’ll appreciate the difference this makes. Just a heads up, this is a General Fit Rear system, so you’ll need to grab your park brake cables separately.

Now, let’s talk fitment. This system is designed to work seamlessly with a stock 9-inch Ford rear end that has a Torino bearing housing. And if you’re wondering about wheel compatibility, it has a 5 x 5.000-inch bolt pattern, which should fit a lot of popular wheels out there.

So, why should you consider the SS4?

• It features a 1-piece, 12-inch directionally vaned rotor that really helps with heat dissipation.
• If you’re pairing it with the Track4 front brake system, you’ll have a killer setup that works perfectly together.
• The fully machined billet backing plate not only looks good but also holds the Banksia park brake assembly securely.
• Speaking of the park brake, it’s a modern design that uses the same shoe as the late model Corvette C5/C6, which is a nice touch.
• Everything you need—hoses, fittings, and hardware—is included in the kit.
• Those 12-inch rotors fit some 15-inch and most 16-inch wheels, but it’s a good idea to double-check with a template to be sure.

Now, let’s dive into the S4 caliper specifics:

• It has four 10mm cross bolts for maximum stiffness, so you know it’s built to perform.
• Stainless steel abutments and noise suppression springs keep things quiet and smooth.
• Hard anodized aluminum pistons mean they’re tough and resistant to wear.
• The internal crossover design helps with fluid dynamics, making the system more responsive.
• With dual seals to meet D.O.T. specs, you won’t have to worry about dust or weather compromising performance.
• The machined logo is hand-painted, adding a bit of flair to the overall look.
• And when it comes to maintenance, it uses a common 4-piston pad for easy replacements (P/N DR1).
• You can choose from a red powder coat finish as standard, but if you want something custom, they’ve got options.
• It’s available for both front and rear, so you can keep that consistent look across your ride.
• For rear systems designed for c-clip style axles, Baer includes their Verislide self-centering brackets, which is a nice touch.
• Lastly, they use the correct banjo-style fittings—no pipe threads here, which is a common pitfall in other kits.
• And just to top it all off, this system is 100% made in the USA with materials sourced right here at home!

So if you’re serious about your braking performance, give the Baer SS4 a look. It’s a solid investment that brings modern technology to your classic setup.
