Overview
The Baer Brakes 4262257FR is a complete SS4 Plus rear disc brake kit for Ford 8.8 inch C-Clip rear ends with a 2.5 inch axle standoff. Its 4-piston S4 caliper is finished in Fire Red and works with a 13 inch two-piece slotted, drilled, zinc-plated rotor, set up for 4 lug wheels on a 4×4.25 bolt pattern.
Baer’s backing plate acts as the caliper mount and houses a modern one-piece park brake shoe assembly, which means the parking brake is built into the rear hardware. The kit is for owners and builders who want a matched rear brake package with stainless hardware and braided lines, with the finish chosen to stand out.
Key features
- Four-piston S4 caliper manufactured in Phoenix, Arizona, from CNC-machined forged or billet aluminum sourced in the US
- Powder coated Fire Red caliper finish
- Hard anodized aluminum pistons, stainless steel abutments and noise suppression clips
- Dual seals guard against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat, pre-assembled with NAS high grade stainless hardware
- DOT approved steel braided brake hoses included with the kit
Signs the old parts are worn
Worn rear brake parts usually announce themselves before they fail. Pulsation through the pedal can indicate rotor thickness variation or uneven pad deposits, while a grinding noise often means pad material is gone. Fluid seeping around a caliper piston or a soft, spongy pedal points to a seal or hose problem that should be addressed right away.
Rubber hoses age with heat and road debris, so look for cracks, bulges or wet spots near the fittings. A park brake that no longer holds on a slope usually means the shoe or cable needs adjustment or replacement. Keeping a simple inspection habit at each oil change makes these problems easier to catch early.
- Scoring or heavy grooves on the rotor face
- Fluid seepage around caliper pistons
- Cracked or swollen rubber hoses
- Park brake that no longer holds on a slope

Vehicle fitment
The kit is not confirmed for any particular year, make, model or trim. It is built for a Ford 8.8 inch flange on a C-Clip rear end with a 2.5 inch axle standoff, and it needs a wheel of at least 17 inch diameter. Review those axle and wheel details against your vehicle before buying.
Confirm your vehicle’s year, model and trim before ordering. Rear ends that are not Ford 8.8 inch C-Clip units with a 2.5 inch standoff are outside what this kit is designed for.
Installation notes
Stainless braided hoses and hardware come in the box and the rotors are pre-assembled, so the hydraulic side of the job is supplied with the kit. Park brake cables are excluded, so confirm that your cable arrangement suits the one-piece park brake shoe. Lay the S135H template against the wheel before mounting, because Baer cannot guarantee fit for every wheel style. Brake work is safety-critical, so have a qualified technician install and test the brakes.
