When it comes to upgrading your ride, the rear brake system from Baer is where performance meets precision. This setup features a robust 6S 6-piston Monoblock caliper, expertly mounted on a 15-inch two-piece rotor that’s been slot and drill treated, plus zinc plated for durability. I’ve put these brakes through their paces, and the stainless steel brake hoses and D.O.T. compliant dust and weather seals make a noticeable difference in reliability, especially when the weather turns sour. The high-grade NAS stainless hardware means you won’t be worrying about rust or corrosion anytime soon, and the pre-assembled rotor saves you a bit of hassle during installation.

Fitment:

• Perfectly designed for the 2014 GM C7 Y-Body rear setup.
• Reuses the factory park brake assembly, so you won’t have to ditch what already works.

Why go for the Extreme+?

• It’s all about that US-made forged MonoBlock caliper—seriously, you can feel the quality.
• What’s cool is that it offers the same sleek look front and rear; Baer’s the only brand doing that!
• Just make sure you've got at least 19 inches of wheel size to fit these bad boys.
• Everything you need is included, from hoses to fittings.
• The 6061 T-6 billet aluminum hat is anodized black and securely bolted to the rotor.
• High-grade U281 fine thread stainless hardware with captured nuts means you’ll have a solid setup right out of the box.

The 6S Extreme+ Caliper Features:

• This isn’t just any caliper; the 6S/6R monoblock is Baer’s flagship, machined from a single piece of US-sourced 2618 forged aluminum.
• It’s the only 6-piston forged monoblock you’ll find for street use—no shortcuts here.
• With stainless steel pistons and noise suppression springs, you get reliability without the annoying squeaks.
• The staggered piston sizes help minimize pad wear, which is a big win for longevity.
• It’s compatible with the common P/N D1247 or DR11 race pad backing plate, shared by many competition calipers, so you’ve got options.
• Dual seals—dust, weather, and pressure—meet D.O.T. specifications, so you know they’re up to standard.
• The caliper can handle rotors ranging from 13.5 to 16 inches, giving you flexibility in your setup.
• Each caliper features a machined logo that’s hand-painted, adding a personal touch.
• Standard colors are black, red, and silver, but you can get custom colors if you want to stand out.
• They use proper banjo-style fittings—no pipe threads here, just solid engineering.
• And let’s not forget, it’s 100% MADE IN USA with US-sourced materials!
