If you’re looking to upgrade your braking game on your classic GM full-size ride, this Baer 13" Pro+ Rear Brake Kit is a solid choice. It’s got a 6-piston, 6P caliper that’s built tough right in Phoenix, AZ. The caliper is mounted to a 2-piece, slotted and drilled rotor that’s zinc plated for durability. The whole setup is designed to fit most 17” wheels and larger, so you won’t have to worry about clearance issues if you’re rocking some aftermarket rims.

Now, let’s talk features. The caliper uses stainless steel pistons and abutments, which means you’re getting quality that lasts. Plus, it’s got staggered pistons to help reduce uneven pad wear—no one wants to swap out pads sooner than they need to. And with D.O.T compliant dust and weather seals, you can be sure that it’ll hold up against the elements.

The rotors are pre-assembled with high-grade stainless hardware, making installation a breeze. Baer’s unique backing plate serves as both a caliper mount and houses a modern one-piece park brake shoe assembly—pretty neat, right? And yes, stainless braided hoses are included, so you get that added durability and performance.

Here’s what you need to know about fitment: this kit is designed specifically for 1971-76 GM full-size passenger cars with the OE large pattern 10/12 bolt bearing on axle housing ends. That means if you’ve got a Buick LeSabre, Oldsmobile Delta 88, or even a Pontiac Catalina or Grandville from those years, you’re in luck!
