If you’re looking to upgrade your ride’s braking system, let me tell you about the Baer 12" SS4 Rear Brake Kit. This isn’t just any brake kit; it’s designed for those of us who appreciate the finer things in performance. The heart of this system is the S4 4-piston caliper, which is mounted to a solid 12" rotor that’s been thoughtfully slotted and drilled. Trust me, that design helps with heat dissipation and gives you better stopping power when you really need it.

Now, the S4 caliper isn’t just pretty; it’s packed with features that make a difference. It comes with D.O.T compliant dust and weather seals, so you know it’s built to handle whatever Mother Nature throws at it. Plus, it uses the popular DR1 or HB100 pad type, so finding replacements down the line won’t be a hassle. The backing plate is a clever piece of engineering too—it serves as a caliper mount and houses a modern one-piece park brake shoe assembly. That’s right, no more fiddling with separate components.

And let’s not skip over the stainless braided hoses included in the kit. They’re tough and provide that extra layer of reliability. This kit is designed to fit most 16" or larger wheels, so if you’ve got a classic GM A-Body from '64 to '77 with the OE small pattern 10/12 bolt bearings, you’re in luck. It even fits those hybrid 10/12 bolt non-flush mount bearings with a 3.150" diameter.

Features:

• Manufactured right in Phoenix, AZ, the S4 caliper is a 2-piece, 4-piston design.
• CNC machined from US sourced forged or billet aluminum, it’s built to last.
• The powder-coated finish not only looks great but adds durability.
• Hard anodized aluminum pistons, stainless steel abutments, and noise suppression clips mean less noise and more performance.
• With dual seals for dust, weather, and pressure, you can count on consistent performance.
• The rotor is a one-piece design, slotted, drilled, and zinc-plated for that extra edge.

Specifications:

• Fits GM A-Body models from 1964 to 1977.
• Designed for the rear axle.
• Caliper color? Grabber Blue—it’s a head-turner.
• Four pistons in the rear caliper for improved stopping power.
• Vented rotor construction with a diameter of 12.000 inches.
• Grade type is performance, so you know it’s not just for show.
• Includes park brake and cables, making installation straightforward.
• Compatible with a 5x4.75 lug pattern.

To wrap it up, if you own a classic ride like a Buick Skylark or a Pontiac GTO, this kit is worth considering. It’s engineered for performance and built to last, giving you peace of mind every time you hit the brakes. Whether you’re cruising down the highway or hitting the track, you’ll appreciate the stopping power and reliability that the Baer 12" SS4 Rear Brake Kit brings to the table.
