Baer Brakes 4262337B Rear Disc Brake Kit with Park Brake - SS4 12-Inch Black

The Baer Brakes SS4 12" Rear Brake Kit (4262337B) is a complete, bolt-on rear disc brake upgrade engineered for serious street and performance applications. This kit pairs Baer's proven S4 4-piston caliper with a 12-inch, 1-piece slotted, drilled, zinc-plated rotor for dramatically improved stopping power over factory drum brake setups.

The S4 caliper is a 2-piece, 4-piston unit manufactured in Phoenix, AZ and CNC machined from US-sourced forged or billet aluminum. Hard anodized aluminum pistons are paired with stainless steel abutments and noise suppression clips for long-lasting, rattle-free performance. The caliper features dual D.O.T.-compliant seals—both dust/weather and pressure seals—and is compatible with the popular DR1 or HB100 (Hawk) brake pad types.

A key feature of the SS4 system is Baer's unique billet backing plate, which serves a dual purpose: it acts as the caliper mount and integrates a modern 1-piece park brake shoe assembly—a more effective solution than conventional drum-in-hat park brake designs. Stainless steel braided brake hoses are included. The kit is finished with a durable black powder coat on the caliper and is designed to fit most 16-inch or larger wheels.
