If you're looking to upgrade your braking setup, the Baer SS4 rear brake system is worth considering. This isn't just another set of brakes; it's a serious piece of engineering designed for those who want reliability and performance. At its heart, you've got a robust 4-piston caliper paired with a solid 12-inch one-piece rotor that’s been drilled and slotted for better heat dissipation and performance. Plus, it’s zinc plated, so it’ll hold up against the elements.

One of the standout features here is the billet backing plate. It’s not just there to hold the caliper; it also houses a Banksia park brake assembly. This is a big deal because it’s a modern take on the older drum-in-hat systems, which can be a bit clunky. The Banksia setup uses the same shoe as the late model Corvette C5/C6, so you know it’s built for performance.

Now, let’s talk fitment. This system is designed for stock 9-inch Ford axles with small bearing housings, as well as the 8-inch Ford standard bearing housing. You’ve got options for both 5 x 4.50-inch and 5 x 4.75-inch wheel bolt patterns, which is great for versatility. And those 12-inch rotors? They’ll fit some 15-inch wheels and most 16-inch wheels—just be sure to check with a template to confirm fitment.

Why go with the SS4?

• It features that 1-piece 12-inch directionally vaned rotor, which is a perfect match for Baer’s Track4 front brake system if you’re looking to keep things consistent.
• The fully machined billet backing plate is not just for show; it’s designed to hold everything securely, including that efficient Banksia park brake assembly.
• It comes complete with all the hoses, fittings, and hardware you’ll need for installation.

Let’s dive into the S4 caliper specifics:

• It’s got 4 cross bolts for maximum stiffness, so you can really lay into those brakes without worrying about flex.
• Stainless steel abutments and noise suppression springs keep things quiet and smooth.
• Hard anodized aluminum pistons help with durability and performance.
• It features an internal crossover design and dual seals to meet D.O.T. specs, so you know it’s built to last.
• The logo is machined and hand-painted—because details matter.
• It uses a common 4-piston pad for easy replacements (P/N DR1), making maintenance a breeze.
• Available in red powder coat finish as standard, with black or silver options, plus custom colors if you want to stand out.
• And yes, it’s 100% made in the USA with US-sourced materials, so you can feel good about your purchase.

So, if you’re ready to step up your braking game and you’ve got a compatible setup, the Baer SS4 rear brake system is a solid choice. It’s all about performance, reliability, and a bit of that American craftsmanship we can all appreciate.
