Overview
The Baer Brakes 4262257MG is an SS4 Plus rear disc brake kit for Ford 8.8 inch C-Clip rear ends with a 2.5 inch axle standoff. It combines a 4-piston S4 caliper finished in Monster Green with a 13 inch two-piece slotted, drilled, zinc-plated rotor, set up for 4 lug wheels on a 4×4.25 bolt pattern.
The backing plate serves as the caliper mount and also holds a modern one-piece park brake shoe, so the parking brake is built into the rear assembly. The kit is intended for builders and owners who want a complete rear brake package with stainless hardware and braided lines in a bold green finish.
Key features
- Four-piston S4 caliper built in Phoenix, Arizona, from CNC-machined forged or billet aluminum sourced in the US
- Powder coated Monster Green finish
- Hard anodized aluminum pistons with stainless steel abutments and noise suppression clips
- Dual seals guard against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat, pre-assembled with NAS high grade stainless hardware
- DOT approved steel braided hoses included
Choosing the right setup
Matching the rear brake package to the rest of the vehicle matters as much as the parts themselves. The parking brake cable, the rear lines and the wheel clearance all interact, so treat the rear assembly as one system rather than a set of separate purchases. Gather the axle and wheel measurements first, then decide whether any spacers or wheel changes will be needed.
Pad choice is another consideration. A pad compound suited to street driving may fade sooner under sustained trail use, and a trail-oriented compound may feel softer when cold. Keep the front and rear pad types in mind so that braking balance stays predictable as the pads wear.
- Cable length and routing for the parking brake
- Use of wheel spacers and effect on clearance
- Pad compound for street or trail use
- Front brake condition before a rear upgrade

Vehicle fitment
The kit is not tied to a particular year, make, model or trim. It is designed around a Ford 8.8 inch flange on a C-Clip rear end with a 2.5 inch axle standoff, and the minimum wheel diameter is 17.0 inch. Confirm the axle and wheel match before buying the kit.
Confirm your vehicle’s year, model and trim before ordering. Axles other than Ford 8.8 inch C-Clip units with a 2.5 inch standoff fall outside this kit.
Installation notes
The hoses and hardware are supplied with the kit and the rotors arrive pre-assembled, so the hydraulic lines need no separate sourcing. Park brake cables are not in the box, so check that your cable setup matches the one-piece shoe. Use the S135H template against your wheel before mounting, because Baer cannot promise a match for every wheel style. Brake work is safety-critical, so have a qualified technician handle installation and testing.
