If you're looking to upgrade your braking system without sacrificing your 17-inch wheels, the SS4+ rear brake system from Baer is a solid pick. This setup features a robust S4 4-piston caliper paired with a 13-inch, 2-piece slotted and drilled rotor that's zinc plated for durability. You’ll appreciate the stainless steel brake hoses included in the kit, along with calipers that come equipped with D.O.T. compliant dust and weather seals. And let’s not forget about the quality bearings and NAS high-grade stainless hardware that come with the pre-assembled rotor—this thing is built to last.

Now, here’s the kicker: the SS4+ is designed specifically for the 1960-1987 GM C-10 trucks with 12-bolt, 6-lug wheels and C-Clip axles. So if you’re rocking one of those classics, you’re in luck. Just a heads up though, park brake cables aren’t included, so you’ll need to grab those separately.

Why should you consider the SS4+?

• It packs all the benefits of Baer's larger brake systems but fits snugly under 17-inch wheels.
• Great for those who want to keep their 17-inch wheels or for enthusiasts who might want to switch back to a stock look later on.
• Everything you need is in the box—except for the park brake cables.
• The hat is made from 6061 T-6 billet aluminum, anodized in black, and securely bolted to the rotor.
• High-grade U281 fine thread stainless hardware with captured nuts ensures everything stays tight.

Let’s talk about the S4 Caliper:

• It features 4 sturdy 10mm cross bolts for maximum stiffness.
• Stainless steel abutments and noise suppression springs help keep things quiet.
• Hard anodized aluminum pistons give you that extra durability.
• Internal crossover design makes for better performance.
• Dual seals—dust, weather, and pressure—meet all D.O.T. specifications.
• Each caliper has a machined logo that’s hand-painted for a touch of class.
• Uses a common 4-piston pad (P/N DR1) for easy replacements, so you won’t be searching high and low for parts.
• Available in a sleek silver powder coat finish, with custom colors if you want to stand out even more.
• And yes, you can get matching front or rear options for that cohesive look.
• Baer sticks to proper banjo-style fittings—no pipe threads here.
• 100% made in the USA with materials sourced right here at home.
