When it comes to upgrading your ride, the Baer Pro+ Rear Brake System is a game changer. This setup features a robust 6P 6-piston caliper, perfectly paired with a 13-inch, two-piece rotor that’s not just slotted and drilled but also zinc plated for durability. The design includes a unique billet backing plate that serves a dual purpose: it’s not just a caliper mount, but it also houses the advanced bankisa one-piece park shoe. Trust me, this park brake assembly is a significant upgrade over the old drum-in-hat systems you often see. It works more efficiently and feels more reliable when you need it most.

One of the standout features is the stainless steel brake hoses, which are complemented by calipers that come equipped with D.O.T. compliant dust and weather seals. This means you’re getting a system that’s built to withstand the elements. Plus, the NAS high-grade stainless hardware used in the pre-assembled rotor is a nice touch—no cheap stuff here. And don’t worry about the installation; park brake cables are included, so you’ve got everything you need right out of the box.

Now, let’s talk fitment. This system is designed specifically for 1964-1972 GM A-Body models with the Buick, Olds, or Pontiac 10 Bolt and 12 Bolt non C-Clip rear ends. Just make sure your wheels are at least 17 inches to fit this setup—there’s a handy template included to help you verify that.

Why should you go for the Pro+?

• It gives you that sweet, uniform look from front to back—something Baer nails better than anyone else in the game.
• Everything you need is included—hoses, fittings, you name it.
• Those park brake cables? Yep, they’re in the box too.
• You’ve got a 6061 T-6 billet aluminum hat that’s anodized black and securely bolted to the rotor.
• High-grade U281 fine thread stainless hardware with captured nuts means you won’t have to worry about rust or wear.

Here’s what makes the 6P Pro+ Caliper special:

• It sports a striking red powder coat finish, with standard options in black, red, and silver, plus custom colors if you’re feeling creative.
• The two-piece forged caliper design features six cross bolts for that extra strength you want on the road.
• Stainless steel pistons and noise suppression springs keep everything running smoothly and quietly.
• With staggered piston sizes, you’ll notice less pad wear, which is a win in my book.
• It meets D.O.T. specifications with dual seals for dust and weather protection.
• The caliper is versatile enough to accept both 13-inch and 14-inch rotors.
• Each caliper features a machined logo that’s hand-painted for a personal touch.
• Compatible with C5 and C5 backing plates from 1997-2012 Corvettes, making pad replacement easy and cost-effective.
• Available for both front and rear setups, so you can keep that clean look all around.
• Rear calipers are specifically designed with smaller pistons to match the front brakes perfectly.
• The rear systems incorporate a drum-in-hat park brake, and if you’ve got c-clip style axles, Baer’s Verislide self-centering brackets are included.
• Correct banjo style fittings mean no pipe threads here—just solid engineering.
• Custom orders are available for different configurations and piston sizes, tailored to your needs.
• And the best part? It’s 100% MADE IN USA with materials sourced right here.
