If you're looking to upgrade your ride's braking system, the Baer SS4 rear brake setup is a solid choice that I can't recommend enough. This system features a robust S4 4-piston caliper paired with a 12-inch one-piece rotor that’s been slot-drilled and zinc plated for that extra durability. What really sets this apart is the billet backing plate—it’s not just a pretty face; it serves as a caliper mount and houses the Banksia one-piece park brake assembly. This modern take on the traditional drum-in-hat system works way better than what you typically find out there.

Now, let’s talk fitment. This is a General Fit Rear system designed specifically for Buick, Olds, and Pontiac hybrid 10 and 12 bolt axles with Ford 3.150-inch bearings, but do keep in mind it doesn’t come with park brake cables. And you’ll appreciate the stainless steel brake hoses that come standard, plus the calipers are equipped with D.O.T. compliant dust and weather seals to keep everything running smoothly.

Why should you consider the SS4?

• It features a single-piece, 12-inch directionally vaned rotor that enhances cooling and performance.
• This setup pairs perfectly with the Track4 front brake system, ensuring a cohesive look and feel.
• The fully machined billet backing plate is a game-changer, as it also holds the Banksia park brake assembly, making it a modern marvel.
• Speaking of the park brake, it uses the same shoe as the late model Corvette C5/C6, which is a nice touch for those who appreciate quality.
• Everything you need is included—hoses, fittings, and all the necessary hardware are right in the box.
• 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 before you dive in.

Let’s dive into the S4 caliper features:

• Four 10mm cross bolts ensure maximum stiffness, so you know this thing can take a beating.
• Stainless steel abutments and noise suppression springs keep things quiet and smooth.
• The hard anodized aluminum pistons are built to last, and the internal crossover design is a nice touch for performance.
• Dual seals meet D.O.T. specs for dust, weather, and pressure, so you can drive with confidence.
• Each caliper features a machined logo that’s hand-painted—details matter, right?
• And when it comes time for replacements, you’ll appreciate that it uses a common 4-piston pad (P/N DR1), making life easier.
• The standard red powder coat finish looks sharp, but if you want to customize, they offer other colors like black or silver.
• Available for both front and rear, so you can maintain that sleek, matching look.
• The rear systems come with a drum-in-hat park brake, and if you’re dealing with c-clip style axles, the Verislide self-centering brackets are included.
• Baer uses correct banjo-style fittings, steering clear of any pipe thread nonsense.
• And here's the kicker: it's 100% made in the USA with materials sourced right here at home!

So, if you're ready to boost your braking performance and style, the Baer 4302343R SS4 brake system is definitely worth checking out.
