If you’re looking to upgrade your braking game, the SS4 rear brake system is where it’s at. This setup features a solid 12-inch, one-piece rotor that’s both slotted and drilled, which means you get better heat dissipation and improved stopping power. The S4 4-piston caliper is mounted on a fully machined billet backing plate, which not only secures the caliper but also houses a Banksia park brake assembly. This is a step up from the old-school drum-in-hat systems you might be used to; it’s more efficient and works like a charm. Plus, park brake cables are included, so you won't be hunting for parts to make it fit.

Now, let’s talk fitment. This system is designed specifically for the 1967-1969 GM F-Body models that come with the Buick/Olds/Pontiac 10 Bolt and 12 Bolt non C-Clip rear ends, featuring bearing-on-axle ends. No guesswork here—this is a perfect match for your classic ride.

Why should you consider the SS4?

• It’s got that 12-inch rotor, which fits nicely under some 15-inch and most 16-inch wheels—just check with a template to be sure.
• Pair it with our Track4 front brake system for a cohesive look and performance.
• The billet backing plate is not just for looks; it’s built to last and holds that Banksia park brake assembly securely.
• The Banksia park brake uses the same shoe as the late model Corvette C5/C6, so you know it’s reliable.
• Everything you need is included—hoses, fittings, and hardware—so you can hit the ground running.

What’s cool about the S4 caliper?

• It’s built with four 10mm cross bolts for maximum stiffness—no flexing here.
• Stainless steel abutments and noise suppression springs mean quieter braking.
• The pistons are hard anodized aluminum, which is both lightweight and durable.
• It features an internal crossover design for improved fluid flow.
• Dual seals keep dust and weather out, meeting D.O.T. specs for safety.
• Each caliper has a machined logo that’s hand-painted—little details matter.
• It uses a common 4-piston pad (P/N DR1) for easy replacements down the line.
• Standard colors are red, black, or silver, but if you want something custom, just ask.
• Available for both front and rear setups so you can keep that aesthetic consistent.
• The rear systems come with a drum-in-hat park brake for that classic touch.
• If you’ve got C-clip style axles, we’ve got you covered with Baer’s Verislide self-centering brackets.
• And of course, it uses the right banjo style fittings—no pipe threads here!
• Best of all, it’s 100% made in the USA with materials sourced right here.

This isn’t just another brake system; it’s a solid upgrade for anyone serious about their ride. Get ready to feel the difference!
