If you're looking to upgrade your C-10's stopping power, this rear brake system is a solid choice. It comes with the S4 4-piston caliper, which is paired with a 12-inch, one-piece, slotted and drilled rotor that’s zinc plated for durability. What sets this apart is the billet backing plate. Not only does it serve as a sturdy caliper mount, but it also houses the Banksia park brake assembly. This setup is a big step up from the old-school drum in hat systems—trust me, it works better and feels more reliable.

Oh, and don’t worry about the installation; the park brake cables are included, and the system features stainless steel brake hoses. Plus, the calipers are built with D.O.T. compliant dust and weather seals, so you know they’re ready for whatever you throw at them.

Fitment:

• Designed for 1960-1987 GM C-10 trucks with stock GM 10 Bolt and 12 Bolt rear ends, using 5 lug wheels.
• 5 x 5.000 inch wheel bolt pattern.

Why go for the SS4?

• You get a 12-inch directionally vaned rotor that’s perfect for keeping things cool under pressure.
• This system pairs beautifully with our Track4 front brake setup, so you can have a matched look and feel.
• The fully machined billet backing plate is not just for show; it holds the Banksia park brake assembly securely.
• The Banksia design is a modern twist on the drum in hat, using the same shoe as the late model Corvette C5/C6, which means it's proven and effective.
• Everything you need is included—hoses, fittings, and all the hardware to get you rolling.
• Those 12-inch rotors fit some 15-inch wheels and most 16-inch wheels, but just double-check with a template to be sure.

What’s cool about the S4 Caliper?

• It’s got four 10mm cross bolts for maximum stiffness, so you won’t have to worry about flexing under heavy braking.
• Stainless steel abutments and noise suppression springs mean quieter operation.
• The pistons are hard anodized aluminum, which is lightweight and resistant to wear.
• Internal crossover design keeps things neat and tidy.
• Dual seals—dust, weather, and pressure—meet D.O.T. standards, so they’re built to last.
• Each caliper has a machined logo that’s hand-painted, adding a bit of flair.
• Uses a common 4 piston pad for easy replacements (P/N DR1), so you won’t be hunting down obscure parts.
• Available in a silver powder coat finish, with standard colors like red, black, or silver. Want something custom? Just ask!
• It’s available for both front and rear, so you can keep that consistent look.
• Rear systems come with a drum in hat park brake for that added convenience.
• For c-clip style axles, it includes Baer’s Verislide self-centering brackets, making installation a breeze.
• And you won’t find any pipe thread here; we use the correct banjo style fittings for a reliable connection.
• Oh, and did I mention? It’s 100% MADE IN USA with materials sourced right here, so you know you’re getting quality.
