If you’re looking to upgrade your braking game, the Baer SS4 rear brake system is a solid choice. This setup features a robust 4-piston caliper paired with a 12-inch one-piece rotor that’s drilled and slotted for better heat dissipation and performance. What really sets this system apart is the billet backing plate. It’s not just a pretty face; it also serves as a mount for the caliper and houses a Banksia park brake assembly. This modern design is way more efficient than those old drum-in-hat setups you might find on other systems.

Fitment:

• Designed to work with stock 9-inch Ford axles with small bearings or 8-inch Ford axles with standard bearing housing.
• This system has a 5x5.000 inch wheel bolt pattern, so make sure your wheels match up.

Why go for the SS4?

• The 12-inch rotor is directionally vaned, which helps with cooling and performance during hard stops.
• If you’re also considering upgrading the front brakes, this system pairs perfectly with our Track4 front brake setup.
• That fully machined billet backing plate? It’s not just for looks; it holds the Banksia park brake assembly securely in place.
• The Banksia park brake is a modern twist on a classic design, using the same shoe as the late model Corvette C5/C6, so you know it’s reliable.
• Everything you need comes in the box—hoses, fittings, and hardware, so you won’t be scrambling for parts mid-install.
• Those 12-inch rotors fit some 15-inch and most 16-inch wheels—just double-check with a template to be sure.

The S4 Caliper Features:

• Built with 4 sturdy 10mm cross bolts for maximum stiffness, so you know it’s not flexing under pressure.
• Stainless steel abutments and noise suppression springs keep things quiet and smooth.
• Hard anodized aluminum pistons resist corrosion and wear, ensuring longevity.
• Internal crossover design for better fluid flow and response.
• Dual seals that meet D.O.T. specs for dust, weather, and pressure protection.
• Each caliper features a machined logo that's hand-painted for a touch of class.
• Uses a common 4-piston pad (P/N DR1), making replacements a breeze.
• Available in a sleek silver powder coat finish, with standard colors in red, black, or silver—custom colors are also an option!
• Rear systems incorporate that handy drum-in-hat park brake for added convenience.
• If you have c-clip style axles, you’ll get Baer’s Verislide self-centering brackets included.
• Correct banjo-style fittings are used throughout; no pipe threads here!
• And the best part? This system is 100% made in the USA with locally sourced materials.

With the Baer SS4 rear brake system, you’re not just getting a brake upgrade; you’re investing in performance and reliability. Whether you’re hitting the track or just cruising around town, this setup is ready to handle whatever you throw at it.
